then what exactly is going to be the deterrent against criminals with guns that want to cause a massacre? are these people supposed to just say 'hey man, dont shoot me pls k tnx' and be on their way? fact is, if people want guns, the law wont stop them from getting a gun if they really want it, and only others carrying a gun will be enough to stop anyone looking to take as many lives as they can in any given setting.

I think the intention of controlling and regulating guns is good initiative. The problem is the market that can not be controlled, always existed and will always exist, there will always be people selling arms and buying them even if there is control.
