It's a sad thing that your opinion will soon be discredited on the basis that you do not know the fact that automatic weapons are much more strictly controlled in the US, and that they are very rarely used by criminals.
I also live in a country with a strict gun control (to get a gun, apart from a plausible reason to own one, doing an expensive course on gun usage and safety, tons of paperwork, psychological tests and similar stuff, you also need to have one of the 16 county sheriffs to approve, and they usually don't). The result is 20 homicides using guns last year, in the country of 40 million. Recently I was having a lunch in a bar, during which two policemen entered the bar, also for a lunch. I have seen their guns at their belts, and it made me feel just as uneasy as when taking night bus home, with drunk people shouting insults at each other, even though I knew that they would only use guns to protect me.
