[Oni]

Oni is a fucking genius.

Basically saying what I was going to say:

If you take away guns, all the people who care about the law and rightfully own a gun will give up their guns, but the people who will be murderers, will have guns as they don't care about the law.

Taking away guns because of bad guys -> Bad guys don't care about the law -> Bad guys will have guns anyways

Taking away guns will have more robberies and home invasions as robbers will break into houses knowing the homeowner has no guns.

To be quite fair, I'd exploit the situation too. If was a criminal and I knew I was one of the few people with a gun still, I'd definitely use that to my advantage. In the United States, where there are over 300 million firearms, it's ridiculous to think guns will all vanish if they are made illegal. I'd hate to be defenseless.
