On motoring: Driving too fast is dangerous... many abide by the speed limits, but some do not. Therefore, "speed limits don't work". Ripsnort's solution - abolish speed limits so that no law is being broken.

Gun control laws in Britain DO work. They just don't work
perfectly. The fact that our gun laws work is why we have fewer than 100 gun deaths each year, whereas America always has many thousands - more than 13,000 in some years.
Our criminals are no better than yours. If we were to enact the "Ripsnort Remedy" by doing away with gun control laws because they "don't work", we would have a bloodbath, and we too would have thousands of gun deaths each year instead of fewer than 100.
Rip - glad to see you're reading a British broadsheet newspaper - does wonders to improve one's grammar and spelling. The bad news (and you're not going to like this) is that the Guardian is possibly the most left wing (ie LIBERAL) broadsheet in Britain.
