The technology for firearms exist, they will always exist now. If someone truly was willing and dedicated to kill people with a gun, they will. You can make a gun with the right materials, though obviously not the same craftsmanship as a manufacturer.

I can totally see how banning guns can save lives: If a parent, or roommate, etc, owned a gun, and someone who knew that completely legal gun was able to be reached and used to kill innocent people. Then yes, banning guns would have stopped that. But if they are, then there's a small line that guy needs to cross: to reach out to whoever to find an illegal weapon.

I for one believe they should be legal, and I also believe that if someone wants to own one, they do their damned homework and train in the ways of a gun, that would save more lives than anything else. Reckless use of a gun is stupid and deadly to the gun owner him(her)self. Would be like a knife wielding junkie going against a samurai, if you do not know how to handle a gun, or handle being under pressure, you are the junkie.

Guns don't kill people, people kill people ..... with guns!
