The electoral war over crime.

Up until now there's been something of a phony war instead of anything approaching all-out combat between Labour and the Conservatives in the fledgling election campaign. Sure, there have been skirmishes over Ashcroft which have involved plenty of claim and counter-claim, as well as more than a little obfuscation, and individual launches on policy from both parties, especially from the Tories, which for the most part seem to have failed miserably but we've thankfully yet to see anything on the scale of say, Jennifer's ear, although there's still more than enough time for such low skulduggery masquerading as a serious issue to come to the fore yet.

The closest we've probably come has been the Tory insistence on using statistics on violent crime which are strictly non-comparable. This started when Tory candidates were sent information from Conservative Central Office which compared the number of recorded violence against the person stats of a decade ago with those of 2008-09. These packs failed to make clear that the way the police recorded violent crime changed in 2002 - whereas then the police decided what was and what wasn't a violent crime, which led to accusations that they were fiddling the figures, this was changed to the victim deciding whether or not the incident they were subject to was a violent offence. This, predictably, has led to a huge inflation in the number of recorded violent offences, as any such subjective change is likely to. According to the stats given to the local media by Tory MP Mark Lancaster, there had been a 236% rise in violence against the person in Milton Keynes, going from 1,790 offences in 1999-2000 to a staggering 6,015 in 2008-2009, or as Mark Easton noted, a violent attack every 90 minutes. Thames Valley police themselves objected to this crude comparison, pointing out that the figures were now incomparable, as well as illustrating how the change in recording has ludicrously boosted the figures: they judged that there had been just 81 victims of serious violence in MK, with around 2,000 victims of low-level assaults where a minor injury had occurred, while the violence against the person stats quoted by Lancaster included a dog being out of control in a public area.

Despite a reprimand from the UK Statistics Authority that using incomparable statistics in such a way was "likely to mislead the public", the Conservative shadow home secretary Chris Grayling was unrepentant and has come up with a novel way to get around such minor quibbling: he asked the Commons library to take the violent crime stats from 1998-99 and apply the new counting methods, which he then compared with those from 2008-09. Quite how they performed such a trick when, as noted above, it's the public themselves that now decide what is and what isn't a violent offence is unclear, and it seems destined to remain opaque as the Tories have failed to publish their research in full, instead giving it only to sympathetic newspapers. The library's conclusion was that the new figure for 1998-99 would be 618,417, as compared to 2008-09's 887,942, or a rise of 44%. Certainly not as startling a rise as the 236% in Milton Keynes or the previously claimed 77%, which was also based on statistics which expressly said they were not to be compared and which were also misleading, but still a very serious one.

Naturally, these figures have been ridiculed by Alan Johnson during Labour's own press conference today on crime policy, but it's hard not to conclude that both parties are, as usual, equally guilty. This is after all the same Labour party which produced the knife crime figures just over a year ago which were heavily criticised by the same UK Statistics Authority which has lambasted Chris Grayling. While the British Crime Survey is by far the most authoratitive source on crime statistics with its huge 40,000+ sample, and which the Tories almost never quote from because it suggests that crime and especially violent crime has dropped off a cliff since a peak in the early 90s, both sides only cherry-pick the figures which suit their needs best. There are flaws in the BCS, such as only recently specifically recording incidents with knives, and how again it has only just started interviewing 10 to 15-year-olds, but it remains superior to the police recorded stats both because it records offences which were never reported to the police or which they missed, while also remaining almost completely free of potential bias. It may rely on the honesty of the respondents, but with a sample the size of 40,000 any attempts to deliberately interfere with it are hardly likely to be significant. After exchanging more letters with Grayling over his newly obtained figures, the UKSA pointed out that while his new research is from a body which provides "professional statistical advice", he'd still be advised to make reference to the BCS, something which Grayling has not done when sharing his new findings.

If however Tory crime policy is indicative of Grayling's approach to statistics, being dishonest, crude and punitive, then as we've suffered over the past close to 13 years, Labour's reign of authoritarian solutions to far more subtle and complicated problems seems forever destined to continue. Johnson was today defending the government's indefensible position on the keeping of the genetic profiles of those arrested but not charged or found innocent of any offence for 6 years on the DNA database, the government's attempt at reaching a compromise following the European Court of Human Rights' ruling on the case of S and Marper. They claim that if the Tory policy of only 3 years was in place that 23 murderers and rapists "would have gone" free, a ludicrous and risible position to take which ignores that old fashioned police work would have had to have been used rather than just relying immediately on DNA records, and which does nothing to prove the efficacy of a database which is now the largest in the world. Alongside the ridiculous proposals to chip all dogs and make all owners insure their animals to tackle what is a tiny problem of dangerous breeds, a statist overreaction which only a Labour government which has been in power too long could possibly think was appropriate, the unworkable fantasy that there could be some sort of "alarm" when a known paedophile goes online, and the cynical ending of the early release scheme just before the election, the choice between one group of authoritarians and another, one of which will sadly gain power, is just one of the low points in what is shaping up to be a truly dismal couple of months.

Your yearly crime stat porn post.

It's that time of year again when the press, politicians and fools like me with too much time on their hands try to make sense of the 195 page Crime in England and Wales document (PDF), which contains both the results of the British Crime Survey and the police's own records. For those unfamiliar, the two compliment each other: the BCS ensures that offences not reported to the police are still recognised, while the police's figures are especially authoritative when it comes to the most serious crimes, as well as providing a snapshot, in these New Labour days of targets, of what they're currently being ordered to focus on.

As always, the figures have thrown some curveballs. After seemingly inexorably rising, murders dropped by a quite astonishing 17%, from 784 to 648. A Home Office statistician suggested that this might be to do with advances in treatment, but if that was the case then we would have expected attempted murders to have either risen or remained stable; instead they dropped too, from 621 to 575. It's worth remembering that the larger American cities often have homicide rates between 300 and 500; New York last year saw 516. The claim only a couple of weeks ago, remember, was that the UK was the most violent place in Europe and also more violent than the US and South Africa.

Both the BCS and police figures, predictably then, show a decline. Violent crime fell by 4% on the BCS, although it was not statistically significant, while it fell by a further 6% according to the police figures, accelerating the falls of last year. As for those all important knife crime figures, apart from a statistically insignificant rise of 1% on the BCS where knives were used in violent incidents, it fell again on all the main measures with one further exception, as it did last year, despite the media coverage which gave the impression that every teenager walking the streets was tooled up and waiting to shank the first person they came across. Murders involving knives declined from 270 to 252, although attempted murders went up slightly from 245 to 271. Robberies involving knives similarly declined from 17,058 to 16,701. Admissions to hospital as a result of assault by sharp object, recorded by the NHS, also fell by 8%. Likewise, gun crime also declined, according to the police figures, by 17%. Firearm injuries also fell by 46%.

Crime as a whole, depending on which you prefer, has either remained stable, according to the BCS, or declined by 5% according to the police's figures. The most interesting differences, and perhaps most revealing, are on burglaries, theft from the person and robbery. Most presumed as a result of the recession that such "property" crime was likely to rise, with those who were previously just making ends meet perhaps being forced into far more desperate measures. Instead, if you were to rely just on the police figures, the only very slight confirmation of that "known known" was that burglaries rose by a not statistically significant 1%, although across the country the figures vary massively. The BCS however, while confirming that burglaries remained stable over the past year, found that there was a 25% rise in theft from the person, compared to a 12% decline in the police's figures, with robbery also down by 5%. The figures on bicycle theft perhaps explain the difference: the BCS saw a 22% rise, while the police figure remained stable. It seems that most no longer expect the police to do anything about the theft of a bike, and that they'll also expect they'll never see it again regardless, hence they don't bother to report it. Other explanations are that some don't report the likes of pickpocketing because they're too embarrassed to do so, or by the time they realise they've been robbed think there isn't a point in doing so. Clearly however this is a cause for concern: it's these life affecting sort of thefts that most influence a person's view of crime, and if people don't believe the police can do anything about them their entire faith in the system is liable to break down.

As last year, the impression of the public when it comes to crime is hugely at odds with the statistics. 75% this year believed that crime had increased nationally, while only 36% thought that it had increased locally. Similarly, 51% thought that they lived in an area with lower than average crime, 39% thought they were about average while only 11% thought the crime in their area was higher than nationally. Even more striking were the figures when it came to knife and gun crime: 93% thought the former had gone up nationally, incredibly unsurprisingly, while 86% believed the latter had. In fact, as we have seen, both had fallen, but you can hardly blame anyone for thinking the opposite when there was so much attention on the number of youth murders in London, which now seem to have been a blip (although the schools only break up this week), however distressing and troubling a blip.

All of this just reinforces the fact that when tabloids, especially the likes of the Sun portray the country and especially the cities as places where the "yob" is in charge or "mob rule" pervades, all they do is make people ever more fearful for no good reason. The chances of becoming a victim of crime remain historically low, even though it increased this year from the lowest since the BCS began of 22% to 23%, down from 40% at its peak. While we shouldn't be complacent, it remains the case that unless we want even more radical policies, either liberalisation (i.e. drug decriminalisation) or an increase in draconian punishments, the crime rate now looks likely to have stabilised, and the scaremongering accordingly ought to be brought into touch.

Cooking the crime figures.

It's incredibly tempting to dismiss what appears to be little more than a misunderstanding based on confusion over what is and what is not grievous bodily harm with intent when it comes to recording crime as an understandable mistake and leave it at that. After all, the 22% rise in most serious violence against the person which comes from reassessing the figures involves just 1,000 more offences (PDF). As Mark Easton, and almost no one else additionally points out, with that 22% rise, accordingly there is a drop in the other offences against the person stats of 11,000, or 10% in offences with injury or 4% in offences with no injury. The figures as a whole again show a further drop in overall crime of 6% - on both the police statistics and the British Crime Survey interviews. The only real rises are a 28% rise in attempted murder with a knife, a further 8% rise in drug offences, again most likely down to cautions given for cannabis possession and a 17% percent rise in the BCS figures in theft from the person. Overall, the risk of becoming a victim of crime is unbelievably, considering the media coverage, at the lowest it has been since the BCS began in 1981 at 23%. Broken Britain this ain't.

You could however predict what the response would be to what is not lies, not a conspiracy, but honest mistakes, the classic cock-up. The government is not to blame; if anyone is, it's the police and Crown Prosecution Service for the complexity of what both consider as GBH with intent and what is not. No one as a result of the statistical errors was given a lesser sentence or charged with a lesser offence; the only crime committed here has been one of hubris. The government itself has become, quite rightly, it can be argued, increasingly proud of the fact that by both measures crime has dropped by a third since 1995. Why this has happened can be argued over, and whether Labour's policies are responsible is equally uncertain, especially considering that across the Western world over the same period crime has generally fallen, but any government regardless of hue would be trumping what has happened. Last time round however the government went too far, especially in the face of the rise of teenagers being stabbed to death on the streets of London,
and played up the fall in crime to such an extent that there was almost bound to be a reckoning come either the first rise, whether due to recession, which as the figures bear out has not yet happened, or the first mistake, which has come far sooner than they imagined.

Regardless of what any newspaper or politician will say, this will broadcast just one message to the public: that the crime figures can fundamentally not be trusted. It doesn't help when the Sun for example directly accuses politicians of lying and the police of hiding the true figures as if this was a conspiracy rather than the obvious cock-up, but it's the recounting itself that will cause the damage. It also fundamentally undermines everyone who does consider the numbers to be accurate, whether they be the police themselves, who overwhelmingly do not think that crime is rising, or the academics and policy makers that attempt to turn the evidence into something approaching a strategy.

What is not true is
that people do not believe statistics full stop. They do, but only as long as they back up what they think they already know. A fascinating survey conducted for Louise Casey's crime review found that when one group was told that crime had decreased, 21% said they didn't believe it had. When a separate group was told that crime had increased, not a single person challenged what they were told. Overwhelmingly when told that crime had increased, 42% blamed the government. When told that crime had decreased, just 15% gave the government any credit. The conclusion to be gleaned is simple: the government is on a hiding to nothing. It cannot possibly hope to get across its message that crime has fallen, either because of public cynicism and the general contempt for politicians, or because the most popular newspapers, in some cases certainly because it contradicts their narrative of just how bad things are in Broken Britain, will only highlight the rises while playing down the falls. This is exactly what happened earlier in the year. Also wrong is the Sun's claim in its leader column that people locally believe crime is going up: the last BCS yearly figures showed that two-thirds thought crime had gone up nationally, while just 39% thought it had gone up locally. Most think things aren't too bad where they live, but think they're awful elsewhere. Why this is the case is probably for the exact same reasons as why the government cannot get its message across.

Something of an answer to this would be to make the gathering and presenting of the statistics on crime completely independent and also transparent. The government and the statisticians need to stop fiddling around and changing the way the figures are counted so that they're not comparable over the long term, something they seem obsessed with doing, even if it is generally for good reasons. This won't stop the tabloids from screaming blue murder every time the figures go the wrong way, and it won't stop them resorting to the tawdry tactics
of reaching for comment from the highly unrepresentative victims of crime which they always do, but they quite clearly need to be depoliticised. With a government however that is committed to politicising security policy, something on which bipartisanship is vital, and when control from the centre is ever more formalised, this seems ever further away than ever.

Crime stat porn and thoughts connected.

Try as they did, opposition politicians yesterday were fighting a losing battle in trying to get some sort of advantage out of the latest crime figures. With the apparent rise in knife crime and teenagers killing each other in record numbers in London, it ought to have been a reasonably easy task. The figures though told a completely different story, and one which is also increasingly difficult to dismiss: after stabilising over the last couple of years, the large falls once again accelerated in 2007/08. Crime as recorded by the British Crime Survey (PDF, references are made throughout the post to the relevant pages), more authoritative because of its huge over 40,000 survey sample showed it to have fallen by 10%, while police recorded crime fell by 9%. In fact, the only figures to show a rise were homicide, which rose by 2% from 759 to 784, drug offences, which were up 18%, mainly because of the continued, possibly soon to end confiscating and warn policy on cannabis and gun offences, which also rose by 2%. Everything else, as recorded by both the police and BCS, either remained stable or fell.

Dominic Grieve, David Davis's replacement as Tory shadow home secretary tried to claim that violent crime had risen by "80%" under Labour, but this ignores the fact that violent crime as measured by the BCS has fallen by an astonishing almost half since 1995, 48% down. Because of the way the police recorded crime changed in 2002/03 figures are now not comparable prior to then, but while the police recorded a 25% rise in violence against the person between then and 2005/06, this has since fallen by 9% to 0.96 million offences (page 21). Where Grieve got his 80% figure from is a mystery.

It was instead left to the tabloids to shriek about the figures which previously they hadn't much cared about. They mostly played down the collected for the first time figures by the police in which knives were used in a crime (attempted murder; wounding with intent to do grievous bodily harm (GBH); wounding or inflicting grievous bodily harm (i.e. without intent); robbery of business property; and robbery of personal property) which totalled 22,151 attacks or offences in total (page 75), which showed that more than 55% of police recorded crimes involving a knife took place in either London, Birmingham or Manchester, while in large areas of the country there were by comparison a tiny number, such as in Cumbria where there were 73, North Yorkshire in which there were 66, Norfolk 67 and Dorset 47 (the Guardian has a handy interactive map), to instead look at the BCS figures on violent crime involving a bladed instrument.

The BCS in total recorded 2,164,000 violent incidents against adults in England and Wales in 2007/08 (page 62). Of these, 6% involved a knife (page 63). Extrapolating from this, this is where the headlines and leading paragraphs of around 130,000 offences involving a knife came from. Further distorting and potentially worrying people, this was then broken down to 350 a day or to a "knife attack" every four minutes. It doesn't matter that these figures are essentially meaningless when you can't get a full rounded figure in the first place from 6% of 2,164,000, they nonetheless occupied the front pages and screamed about the reality of life in "Blade Britain". What few of the papers bothered to go into was the caveats that are involved in these figures which help greatly in understanding that these are simply not instances of people getting stabbed or even attacked. For example, just over 51% of all violent incidents resulted in no injury whatsoever (page 72), while the most common injuries that were suffered were minor bruising or a black eye (28%), severe bruising (15%) and cuts (13%) (page 73). In only 12% of violent incidents was any form of medical attention sought, with 9% seeing a doctor and just 1% requiring an overnight stay in hospital. Of the 2,164,000 violent incidents, around a third were incidents of stranger violence (page 71), while another third was, more surprisingly, acquaintance violence. Domestic violence accounted for one in six violent incidents. The overall risk of being a victim of violent crime was 3.2% (page 70). The overall risk of being a victim of any sort of crime was 22%, the lowest since the BCS began in 1981.

It wasn't even as if the tabloids could claim there had been any huge rise in knife crime, as the statistics in fact mainly show the opposite. The use of knives in the 2,164,000 violent incidents was actually down 1% to 6% from the 2006/07 survey, although the figure was not stastically significant (page 76). The figure involving knives used in violent incidents has also stayed broadly stable since 1995, hovering around or below 8%. Also interestingly, the Metropolitan police, which have been collecting figures with crimes involving knives separately from other forces also recorded a fall. The Met recorded 10,220 knife enabled crimes in 07/08 (page 76), 16% down on last year, figures which were 4% down on the previous year. As korova on Mask of Anarchy points out, mostly ignored but also in the figures is the fact that 7% of violent incidents involved a blunt or "hitting" instrument, which can do potentially as much if not more damage than a knife, but which have been lost sight of in the current atmosphere. We are not then suffering from a knife crime epidemic. The reality according to the figures is that we're experiencing a stabilising effect and no real rise in knife crime. What is happening without question is that young people, especially in the cities are carrying knives, and are increasingly prepared to use them, as the latest terrible death of a teenager shows. That's the main reason why we're currently having such potentially adverse and over the top media attention, along with the fact that alongside the mostly black victims, three of those who have died have been white, middle class, and either had telegenic, hospitable and eloquent parents or semi-famous relatives.

The problem is, as we all know, that fewer and fewer people believe the statistics. Two-thirds believed that crime had risen over the past year, but as often seems to be the case, only 39% believed that crime had risen in their area. The same pattern seems to apply to those who think that the NHS is nationally getting worse even while they think that their local services are actually fairly good. It's hard not to link this directly with media coverage: faced with the number of young deaths in London, who wouldn't after all believe that crime is rising? With all those front pages this morning, again, who wouldn't believe it also, even if they read the articles in detail, where most do make clear that according to the statistics, if they care to believe them, that crime has fallen apparently spectacularly? This is where Louise Casey's recommendation for a independent statistics board might help, but only if it potentially has teeth which can challenge the media picture.

Also related but also without an answer is exactly why crime is falling so significantly, again, if we are to believe the statistics. This incidentally isn't just happening here but across the Western world, so unless everyone's on the fiddle it's an almost global picture. The Guardian's editorial suggests the reason is that we've all gotten richer but that we've also gotten older, and crime, as the BCS itself shows, is predominantly a young man's game. Criminologists themselves admit that don't know, which in itself is refreshing; others point towards better security. The government's policies also have to be considered; perhaps the record numbers in prison have contributed to the fall in crime? If so, that itself puts those of us on the left who think there are already too many people in prison, let alone without adding more capacity, especially when those inside cannot get adequate treatment for the drug problems and mental health issues which so contribute to crime, in a difficult position.

In summary, there is no knife crime epidemic, or at least one isn't reflected in the statistics. Crime itself is at its lowest point for a generation, and again, although it doesn't feel like, Britain is now probably the safest it's been overall since the early 1980s. The real difficulty is in convincing the public themselves that this is the case, and not exaggerating the real problems we do have into a picture of a broken society. The biggest difficulty of all is that we don't seem to have any answers whatsoever.
