iuliand: I'm not joking.
First, bearing arms is just one more "right" that US grants to it's citizens by constitution. Ok, and what is the benefit of this right? Isn't this encouraging people to make justice for themselves? I don't follow the usefulness of this right. Maybe in the old days, but in modern times I can see only disadvantages. I think that the defenders of this right are conservative people who just like to have this right as something to show off in contradiction to citizens from other nations.
And if you ask me about gun control in Romania, I can tell you that here we have absolutely no case of shooting in schools or on the streets, and this speaks for itself why civilians should not be allowed to bear fire arms.
Here are allowed only hunting weapons and gas powered weapons and to have one of these you need a permit, you have to pass some psychological tests and you are required to keep them locked when not using them. It is your responsibility if someone else takes your weapon and makes something stupid.
So in this respect I think that the law here is better. I can sleep better knowing there is no danger that a psycho will start shooting at my kid on the street. And I feel no need to bear a firearm.
This is yet another case of people applying cultural biases.
With regard to your first paragraph: Yes, many morons do view it as an excuse to act like cowboys (see "The NRA"). But the essence behind the right is essentially self-defense. It was originally intended to make militias legal (a necessity at the time) and later evolved to represent defending oneself in cases where the law cannot arrive in time (the "wild west" as it were). And while it is questionable if this is still needed, that is a different debate.
It is NOT about "taking the law into your own hands" and the like, regardless of what many morons want to believe. It is about being able to go hunting and about being able to defend yourself in a case where the law might not be able to help (home invasions, shopkeepers getting robbed, etc). It is a hard distinction to understand, but that is one of the cultural differences.
Second/third paragraph: Actually, those are exactly the laws that I want, but with an additional provision for pistols (of a reasonable caliber) for the purpose of self-defense. The problem is that there are the morons who think all guns need to be banned (because if nobody is allowed to legally own a gun, all the illegal firearms will magically disappear :p) and the morons who think they need a .50 cal machine gun to defend their one-room apartment.
Last paragraph: Your conclusion doesn't follow. There is still a danger that a psycho can start shooting at your kid on the street. What if someone who passed said psychological tests has a nervous breakdown at a later date?
Or, what if someone gets a firearm illegally?
