The general notion is that youngsters carry knives for defence, as so many carry them they are always prepared. I lived in a YMCA for 5 years and I know at least 70% of the kids up to, say, 21 carried knives and all claiming it was for defence. If that is so then whoever draws the first blade must be the aggressor, which makes a mockery of the defence cop-out. Kids draw blades to intimidate another and look big or they are losing a scuffle and resort to stabbing. Still the government has a superb answer. They're going to accumulate the figures on knife crime separately. That will solve the problem overnight.
