Early last month the Met announced that, "Stabbings and shootings among young people have fallen since the launch of the Trident Gang Crime Command just over six months ago." You'll remember the "crackdown" fanfare at the time, prompting in me disobliging fears that there would be more copstrut public relations than real, lasting action against the territorial violence becoming ingrained in parts of London among the young. And, anyway, how were we defining "gang violence" in the first place?
