Was Cho Seung-Hui Schizophrenic?

Hot Air, who has by far been doing the best job covering the VTech mass killings, has a post suggesting that the killer was schizophrenic. Well, he was obviously very sick in the head, but an interesting idea.

I just hope we don't end up blaming this on a disease. These killings weren't the fault of disease or the Second Amendment or politicians or the university or Islam or video games; the blame rest solely on the shoulders of the deranged maniac who pulled the trigger and killed some 32 people.
