@Nulle - I guess you are glad that the USSR did not have such gun laws when the Latvians wanted to have their say!
@Eric - No, they may not have riots in the USA, but they have gang crime, more murders per head than any country in Europe and much more drugs crime. But I know that you think the USA is right no matter what they do, so I suppose you are glad that all that is now happening in Russia too.
The UK prefers to keep the police unarmed so that criminals will not arm themselves as a counter measure. For the most part it's working quite well. It's extremely unusual for British policemen to be killed. Criminals are not walking around with arms. The worst problem in the UK is teenage hooligans who carry knives.
