why is the boston bombing an "act of terrorism" while the aurora movie theater shooting is a "mass shooting"
The difference in the way the media and the public in general has responded to the bombing versus the shooting interests me. It goes without saying that both are horribly tragic, senseless, truly twisted acts. But, is it simply the method of injuring and killing that separates one act from another?
