Okay..i stopped reading somewhere page 2 in the middle and just began to post because i can guess it just gets more to flamewar and all the same points are brought over and over, so lets cover all of it in one turn, shall we? Okay..lets start.
1) The Problem with Guns and the US is a very simple one. I do understand the reason People get a gun and why its even allowed in the first place but lets see a simple logic here, dont worry, its not hard on the brain and i'll explain it simple. The Fact that the US are getting bullshit thrown at them because of their Laws regarding owning a Gun stems from the Fact that no other Country has any similar Law, why not? Because they have no need to, in the US you are allowed and sometimes required to have a Gun simply because everyone else has, in the UK or Germany or every other Country doesnt have that, no fear of getting shot=no need to carry a gun. Ban Guns or have every Person being a certain age and meet very strict rules before even giving them a Weapon, in Germany, after the Erfurt Massacre (which was also blamed on Games) they tightened the Law to actually OWN or IMPORT a gun into the country, still possible to get one, but quite harder. Okay, moving to the next Point.
2) Blaming Games is really simple as well, because the logic behind it is as old as the first hate speeches, lets recount. TV was invented and then came the movies and shows etc, so People were like "TV is bad" like they do now with games, so far so good, now why is that the same? Because nowadays having a TV is common, everyone owns one or at least has seen one to know its NOT bad. Same goes for Music and everything else, as soon as enough People know its not as the Media tells us they find another scapegoat. Tv to Music and Music to Games, i wonder why they havent said THINKING is bad yet, seeing that many people dont even do that anymore, otherwise there would not be such hatespeeches and god knows what against something at all, unless really proven otherwise. So unless someone starts playing a Game and immidiatly goes on a killing spree the simple idea of it causing any violent behaviour is stupid, if not totally moronic.
So, in case someone expected a Flamepost here and didnt read much of this post, lets make it short. Guns dont kill People. People kill People WITH Guns (or knifes etc) therefore preventing them, especially mentally unstable people, to get a gun will lower said Crimerate, it wont prevent it altogether, but lower it. And yes there is a psychological switch also, killing someone with a gun is easy, its pointing and pulling the trigger. Using a Knife on the other hand, you have to get close to the victim, the victim does stand a fighting chance and can kill you (the attacker in this case) because of being lucky or being stronger whatever. Also looking someone in the Eyes when you stab them scarres the mind more then a simple point&click gunshot. If you want real Psychological Terror however, look at Military Hardware and how easy it is to exterminate thousands of People with the press of one Button.
EDIT: And no this is no rant or flame against any Person in here, Country or Group of People, its just my, somewhat objective (if it can be that, seeing its mine) Opinion on the Matter.
