Albert, your point gets shot down by the fact that criminals only have to make a 10 min ride to get to where they can get a weapon. We have criminals in Spain, sure. But it's quite hard to get a handgun, not to talk about a rifle. Do you know what ETA is? It's a terrorist group, had contacts with IRA when de latter was still active, etc. What do they use? small handguns and old dinamite from minesites. An organized terrorist group, and most of their arsenal is just old revolvers, some 1911s and defective explosives. I think it's a safe bet to say I can walk down the street and I won't be shot.
That's also one of the reasons why lately terrorist attacks in Europe are just trucks running over people. They couldn't get the weapons they needed.
I'm not an anti-gun guy. I love them. But I don't want to be surrounded by people who have de means to shoot me, 24/7.
