David Theroux on the Aurora shootings
He makes some excellent points, at the Independent Institute.
While driving today, I hear a radio discussion on what would be the shooter's chances with an insanity defense, if it could be shown that he was delusional and believed he was Joker. I thought it might have one big problem, assuming Colorado follows M'Naughton, so that the person must be delusional to the point of not realizing that he was committing a crime.
Joker is the villain, the arch-criminal. So if he thought was Joker, then he believes what he is doing is evil and illegal. He's insane, but doesn't believe what he's doing is legal.
(I once knew of a case where there was true M'Naughton insanity, but it ended on a plea bargain. The defendant started a fire in his hotel room, went off to eat breakfast, and upon returning asked the firemen "how did you like my fire?" Clearly, he thought that what he had done would earn the firemen's praise, or perhaps they would advise him on how to improve his form and make the next one better.
