None of which changes the fact that guns do not cause crimes.
Anyone who thinks that guns cause crime and are a thorn to society is a fucking idiot, IMO.
Hypothetically, if guns were unconstitutionally banned from the average citizen, things would potentially get way out of control. People would take alternate routes for slaying one another like homemade explosives, running people over with motor vehicles, shanking, strangling, or whatever else could come to mind. Guns are useful for catching criminals to detectives because of residues and other evidence left behind after the shot is taken.
Guns don't kill, people kill. Let's get it right everyone!
Back to another point from a previous post, if guns were banned to the average citizen like in england, then only the criminals would have them and the rest of us would be fucked.
What I think would help people, is more comprehensive classes on what would constitute a legal cause to engage an enemy in strict self defense.
