1) One evil person does it
2) Evil person gets media attention and hype instead of due punishment
3) Idiot evil people copycat these things, or ramp up the intensity
4) More of the same media attention and hype instead of due punishment
5) Big Media and Government don't care because it turns the people against each other and they can rule us with their elitist Big Brother fists.
We don't have a "gun" problem or a "gun control" problem. Guns were made to do one thing: shoot bullets. We have an "evil people" problem. We have an "entitled criminal" problem. We have a "justice system" problem.
