The movie did not cause this shooting. The theater did not cause this shooting. Comic books did not cause this shooting.
A young man, who is in custody, caused this shooting. The young man is the only one who should be held at fault.
If were going to hold a movie company and theater at fault for a shooting that happened during their film, should we hold the makers of the guns he used at fault since he used their brand of weaponry? Should we demand payments from the ammunition makers who's bullets ripped through those theater goers? Perhaps we could slap the university he attended with a bill, they're the reason he's even in the state. Should we charge the estate of Heath Ledger for his portrayal of the Joker, since this man allegedly claimed himself to be the Joker?
While we're at it, fast food companies should cover the costs of heart attacks, tobacco companies should foot the bill for lung cancer treatments, and auto makers should be the ones covering the costs of traffic accidents.
We can play the blame game all day and find more and more places to point our finger, or we can pin the blame on the 24 year old man who planned and carried out the shooting and leave the bystanders out of this.
