Well, what would you like to discuss? I believe Clinton mentioned on Letterman awhile back that a ban on assualt weapons is going to expire very soon, and it is unlikely that Bush will renew it. I'm not sure if he said what he thought Kerry would do with it if he was president because I heard about the news secondhand.
I personally would not like to see the assualt weapons ban lifted. I know a lot of people (including the NRA) oppose almost any kind of gun control because technically the second amendment doesn't specify any circumstances where the government can prohibit the possession of weapons.
However, I honestly don't believe that assault weapons are necessary for ordinary citizens to have. The purpose of these weapons is to, well, assualt. More specifically, to assualt people. What use do we have for these? These guns are used in war. People mostly own guns for gaming and hunting. Do we really need assualt weapons to hunt a deer?
I do believe that the American people should be able to own guns, even though I never will. However, there should be limitations on the types weapons allowed. We can do all the background checks in the world, but that won't stop someone from recklessly turning a gun on another in a sudden bout of anger. Why give the public guns that are only most practical for killing people?
