Friend for her comprehensive answer, may I tell her that, particularly in my part of north-west London, the gang and gun culture is corrosive and massively dangerous and destructive, not just to the young children dragged into that murderous web but to the rest of us, who are literally caught in the crossfire? What lessons have been learned from the Tackling Guns action programme that can be applied to north-west London?
