Officers are drafting a response which will be sent shortly.

Written response from the Mayor 09 September 2013

MPS records show that the following numbers of people were proceeded against in the period January 2010 - June 2013. The data provides information on people proceeded against (PPA) only, namely those individuals who have been accused of an offence and proceeded against resulting in a detection (i.e.: charge, summons, fixed penalty notice, taken into consideration or caution.)

We are unable to provide the injury class as the injury class belongs to the victim, and not the PPA. There can be multiple victims and PPA on a single record, and there is no way of linking a specific PPA to a specific victim, and thus the injury that they have caused.

The data sets in MQ 2548, 2549, 2553 are irreconcilable with the data sets in MQs 2550, 2551, 2552. A comparison between the number of victims of knife crime with the perpetrators of knife crime would not provide robust outcome. For example, a perpetrator can be proceeded against for multiple offences but would only be counted once.

In addition, knife crime potentially encompasses a very broad range of offences and this causes problems in both the definition and determination of its prevalence. Whilst the data in the table captures crime where the perpetrator was in possession of a knife, it may not be the case that the possession of the knife was the direct cause of the injury sustained by the victim.
