Ohio man pleads insanity in 11 deaths - CNN.com
Of course he's insane! Sane people don't run around raping and killing people. Or blowing up buildings, or setting parks on fire, etc.
I really hate that "not guilty by reason of insanity" is an option. I mean, you either had the weapon in your hand and used it, or you didn't, right?
"Guilty but with the 'crazy' stipulation, and deeply in need of psychological treatment" I'd be able to deal with, probably.
