On "gun free zones" I think this is so obviously an absurd idea I have no idea how anyone could support it. If you have an armed nation you can't just say "if you walk down this street no guns are allowed." Wtf is that???

And yes high levels of knife crime particularly among gangs. Not only that but in London especially, but other cities too, there is still gun crime among those gangs too.

Recently there was a story that hit the news because some gang member accidentally shot a child and this was in a fairly small town in the UK.

To state the ridiculously obvious: criminals don't follow the law.
