It's quite clear based on his youtube videos alone that he is a paranoid schizophrenic, it doesn't take and expert to see that.

Really?

That's quite hard even for professionals to diagnose.

Five psychiatrists gave evidence at Pete Sutcliffe, the Yorkshire Ripper's trial, four saying he was unfit to plead as he was a schizophrenic. The judge believed the other one (hired by the prosecution) and said he could have a normal trial. He was banged up in the mainstream prison system where he was horribly abused for two years before he was (yet again) diagnosed as a schizophrenic and moved to Broadmoor Hospital, where he remains.

Whatever Loughner's problems, I don't think the Tea Party and especially Sarah Palin can escape the consequences of their own insane rhetoric.
