Actually those statistics don't prove that it's the strict gun laws in the UK that prevent everybody getting hold of guns and shooting anybody in sight. Rather the strict gun laws reflect the fact that there's overwhelming revulsion at the idea that guns should be readily available, or should be seen as a normal part of life.

In fact it's not so long ago it was well into the 20th century that there were any gun control laws in the UK, and use of guns was pretty limited even before then.

As has been said here a few times, the problem in the States isn't so much the laws, it's the culture.

As for the NRA, that's only in the hands of crazies because the people who aren't crazy - more especially the gun owners who aren't crazy - don't take it over and turn it around so it supported sensible policies.
