I know what you were saying. I'm claiming that it's irrelevant. After enough driving on the highway, I can forget that the speed limit is 55mph and stop signs still exist. That doesn't mean that you can excuse me blowing through a four way stop at 70mph and hitting another car just because I didn't have malicious intent.

My point is, guns are a bit more dangerous than knives, and the responsibility of the holder should reflect that.
