I read through some of this, and I keep seeing how people say it is so easy to get a gun at a gun show. Maybe those should have higher restrictions, since as all of you say, that is where the criminals get their guns. It is one thing to have a gun and hunt, or just target practice and stuff, but that doesn't mean that you need tons of ammo, and military grade weapons. That recent massacre at the movie theater could have been lessened if the maniac didn't have such a high amount of ammo, and hardly had to reload. When are you gonna have to fire off 10 or 20 15-round magazines? It only takes a couple of shots to kill a deer, if that.
Think about how long it takes to get a license, or even a passport, and then, as all of you are saying, you can just walk into a gun show and pick up a weapon. It shouldn't be that easy.
I recently had a friend kill himself with a gun, his step dad's gun which he thought was hidden. There should be restrictions, and there should be laws, there just has to be a BALANCE and that's all there is to it.
