While I would, hypothetically, prefer he had assumed asphalt temperature - by his own hand, by the hand of one of his intended victims, or by a proper police action I don't care - that he didn't is doubtless due to not doing anything stupid when the police arrived.
The Taxpayers will undoubtedly be out several million dollars over the course of his life to keep him locked up and cared for.
That always bothers me knowing this kind of filth will spend decades living off of the taxpayer's dime.
