Young criminals are increasingly ready to use firearms after a perceived slight to their reputation. One aspect of the "chaotic" new trend is that they shoot to injure rather than kill, aiming at the victim's legs and leaving their rivals with "war wounds".The number of these shootings now stands at 72, more than double the total for last year. Commander Martin Hewitt said the propensity to use "extreme levels of violence for seemingly very little reason" was a new phenomenon. He said that when Operation Trident began investigating gun crime in the black community most shootings were an "offshoot" of criminal activity.Police have seized more than 1,000 guns in London so far this year. While overall youth violence is falling, police say there is a rise in gun crime and, in particular, the number of non-fatal shootings involving turf wars.Many criminals are inflicting "war wounds" on rivals by shooting them in the legs. The number of these shootings now stands at 72, more than double the total for last year.
