If this will work, then British criminals must not be nearly as ingenious as American ones.
I saw a program once about the items prison guards regularly find in cells here. I never knew how much damage you could do with a magazine! (The paper kind that you read).
I can only hope that this idiocy will start to wake the Brits up enough to realize the fallacy in the "elimiate crime by eliminating weapons" arguments.
I'm late to this, but have to point out (will that phrase be outlawed as well???) that when I was being trained as a "baby killer" (i.e.: I was in the US Army), we young, ruthless males were told that a dull, rounded tipped knife is MORE DEADLY than a pointy sharp one. As you viscously thrust the dull, rounded knife into the chest of your target, his flesh tears apart and his organs tear apart in jagged fashion - making surgical repair much more difficult than the neat puncture and slices made by sharp, pointy knives.
These cops in the UK have it backwards!
