R18 - Research on Knife crime statitics

 http://www.citizensreportuk.org/news/2013/06/25/london-knife-crime-offences-by-borough-2007-to-2013/

There has been a significant reduction (-19.7%) in reported knife crime offences from the financial year 2011-12 to 2012-13. With some boroughs notably: Lambeth, Westminster, Brent, Camden, Greenwich, Islington and Merton seeing reductions of over a third. Three London boroughs saw small knife crime offence increases, Croydon, Southwark and Barnet, with Southwark having the highest volume of knife crimes in a London Borough and Croydon the second highest volume.

Interestingly those boroughs that saw some of the greatest reductions in knife crime did not see any real improvement in Sanction Detections rates (police identifying or charging offenders) with only small increases in some cases and indeed a few decreases in sanction detection rates. Given the reduced number of police officers in London boroughs and the minimal year on years change in sanction detection rates; it does suggest that policing and crime detection activity has not really led to the significant drop in knife crime offences over the last year and other factors are probably in play.
