I'm not to blame for these shootings. Stop blaming guns. Stop blaming the media and video games and movies. Some of this is offensive, but it doesn't put a gun in someone's hand and pull the trigger for him. When it comes to politicians I admit it's tempting to blame them.
Politicians do their darnedest to screw up an awful lot of things.
But these shootings are not the fault of politicians. In fact, most agree that none of the gun laws or other measures being emotionally debated in Congress would have prevented any of these killings. That's where moral responsibility lies. They're the ones that did it. The hallmark of a civilized society is individual responsibility.
