I wouldn't say guns are all that available. You have to be 18 to even buy air cannisters or BB's for a BB pistol. You also have to be 18 to buy paintball equipment. At least at major chain stores. I'm not sure if that's a law or not. Now, if you're buying on the black market...that's a different story, but it ain't legal.
Also, I read in another post, someone said they didn't believe in guns knives or other weapons. How do you cut your steak, chicken, carrots, or whatever you eat? just curious
