What I find interesting, (if that's appropriate in cases like these) is, if there are soooo many guns out there, why is no one shooting back? I mean, you rarely hear of anyone returning fire? The assailant is in a crowded venue and is firing for minutes, and the victims are hiding. Is there no one in any of these places with a carry license that can engage the perpetrator? Just doesn't seem plausible with "so many guns on the streets". In a lot of these shootings, as soon as law enforcement engages the shooter, he turns the gun on himself. Perhaps if someone immediately returned fire, it would save lives. Also, by returning fire, gun advocates could enforce the argument that guns are needed for self protection. Just saying...
