While I don't agree with Costas, the line of thought that someone will just do the same thing with a different weapon is asinine. Guns remove much of the human element from inflicting harm on someone. It can be done from a distance and it is the bullet doing the damage, not the actual person. Stabbing or bashing someone's brains in is a lot more brutal. For some people that doesn't matter because they are truly sick in the head, but for a lot of others, they never would have committed the crimes they did without the assistance of a gun.
Shooting someone is easy. You keep your hands clean and its often one shot and done. That's not the case with other weaponry.
Ok....so you essentially make the same points that I did, but in a better way. Read my post again; I said that he could have used another weapon, but the gun made it easier.
I like how some of you guys are playing word games. Sure an AR-15 may technically be classified as a " semi-automatic hunting rifle"....but we really know it is not. AR-15 has two modes: safe or semi-auto; the M16A2 has safe, semi-auto, or 3 round burst. None of the weapons in the M16 family except for the obsolete M16A1 (this family includes AR-15s) has a fully automatic mode of fire. So the only real difference between the AR-15 and the other weapons in that family is 3 round burst; that difference is not enough to classify one as a hunting rifle and another as an assault rifle...they are essentially the same thing. And that's just talking about the ARs and not the other assault rifle type weapons that are out there.
Also FYI the Federal Assault Weapons Ban expired March 2, 2004.
