About Banning Guns
Criminals go outside the law... so they will continue to commit crimes with guns, even if they are banned... so the more people with guns that are law abiding citizens... and who are responsible... this will automatically deter some criminals from committing their unlawful acts, since they themselves know that a good possibility is that they will be harmed or will loose their life.
So the idea of banning guns to stop crime is an oxymoron... do you really think that criminals will think twice about a gun ban?
It is not that the gun is evil or bad... it is like saying that a hammer is evil or bad because you can kill someone with one blow to the temple. Or how about a stick... the temple on your head is a very soft place that can easily be punctured. So sticks are bad too?
It is the user of the tool, not the tool itself.
