What's wrong with the world today? I mean with the recent Colorado theater tragedy... Obviously something must be done regarding guns control here (in the world). I mean why someone would need an AR15 rifle for self defense? With 100 rounds magazines? What's the reasoning behind it? To defend against the chinese army? AR15 being, primarily, an assault and high power rifle.

One more (negative) example: that poor fellow that responded, some months ago, to police knocking (wrongfully) his door, armed with such weapon; he prompted deadly response from the cops. Innocently.

Another thing, don't take me wrong, I'm not blaming on americans. America was/is the leading world nation, and for some time this kind of indiscriminate shooting was the trademerk of America: any disgruntled employee, used to take a gun and "erase" his past. From here on, copycats were everywhere; last one: Norway.

I'm not US citizen, my country allowed (small) guns to civil ownership like 20 years ago, mostly gas variants or balls/rubber bullets. But the use of those is not at all common, nor the mentality to defend against (duck/hide), when we hear some cop used his gun (that like 2 times in a whole year the whole country, to stop some thug fleeing) it's the exception.The only kills we hear by fire arms are hunting accidents or suicides. All those because of a no-gun mentality.
