Look, I don't even know why we're debating this. The guy was responsible for the deaths of thousands of innocent people. Men, women and children. Little babies. He did not deny this – hell, he reveled in it. Wore it as a badge of honor. Dude was guilty as sin. And some whiny bitches are wringing their hands whining and bitching about giving the dude a trial? Give me a break. Putting him on trial would take forever, give him a platform, stir up the crazies... and there's always the non-zero probability he could be found innocent. A trial is fruitlessly pro forma in a case like this.
Obviously – painfully so – George W. Bush should be summarily executed.
