The mental illness defense

PZ Myers has a great article  up on Freethough Blogs about the dangers of criminalizing mental illness and the ease in which it can be used as a defense:

But are we seriously going to diagnose them as mentally ill because they’re terrible people? Shall we slap them into straitjackets and shoot ‘em up with Prozac? 

Because if that’s the path we’re going to take…we can probably lock up a few thousand World of Warcraft players, and I suspect we might easily find a million Call of Duty players who will fit this trivial online diagnosis of psychopathy. Then we can visit the Stormfront site, and get all the members there committed. All those contributors to Uncommon Descent, the intelligent design creationist blog…clearly insane. Especially Denyse O’Leary. I once visited a car forum when I was looking for a recommendation, and was appalled at the racism on display — a significant fraction of Honda drivers are clearly nuts. Oh, and Tea Party members! They all need to be rounded up and put in camps, for their own good…they must be so dysfunctional that they can’t possibly cope with the real world.
