Well, you know that Aurora theatre shooting? That guy had passed a background check.The hand gun is the one used by most ,in the cities,where murders are committed.The automatic rifle is used by mental patients to kill indiscriminately and get the many at once.Checking the mental patients should be the first measure.But then ,are any using their ability to think,or,is this just an emotional venture?
And this is not about making a dang thing safer. This gun thing is all about taking guns from law abiding citizens. It's all about control. Control the population by taking their weapons then anything at all the gov does can be rammed down the citizens throat because even if the citizen objects, he can't defend his objection.
