But as recently as 2008, it was the then Prime Minister Gordon Brown who tried to respond to a rising sense of alarm by holding a knife crime summit while not in full possession of the facts, and David Cameron, Tory opposition party leader as he then was, who described knife crime as an epidemic and Britain as a broken society.
Both politicians were inaccurate to a great extent - or, assuming some public manipulation, do we say 'economic with the truth' - to try to make some political capital, as well as make a bit of real progress maybe, if lucky, from a time of public alarm.
How much more helpful it would be to have a target to reduce knife and violent crime and all those working on that project aligned and communicating progress on a monthly or quarterly basis to the nation at large. There you would be better able to see the start of a focal point for the bereaved and injured to feel involved, and to affect positive change too possibly.
And that completes part 2 of this blog's series looking more closely at how to solve knife crime in this country - and possibly the world. Next time, I'll look at the poverty factor causes knife crime problems and how young people are demonised in Britain leading to misbehaviour and illegal carrying and use of knives.
