So how many mass stabbing killings are there? - I don't know. But what I do know is that UK has a serious problem with knife crime but banning knives for everyone would be an outrageous, moronic assault on liberty.
Public safety overrules a stupid ass 200 year old law - I get what you're saying but you've not really addressed my question, which was ... why should at least some types of guns be banned for everybody, when it's only a tiny minority of gun users who go on shooting sprees? Surely there are better ways of dealing with this problem?
