Now one of the survivors (who as best I can tell was uninjured), Torrence Brown Jr, is suing the movie theater. Sue the innocent, because you'll get nothing out of the guilty. Yeah that's always a good policy.
I also love the one about suing the movie producers. Just days after you purchase the product, you suddenly decide it's the cause of injustice. Tragedy (or the promise of great riches?) tends to change your direction, I guess.
