He cannot possibly be sane.
I don't care how much planning he did beforehand - he cannot possibly be sane.
Otherwise, I am absolutely scared to death. How do you go to a movie or a ball game or anywhere where people congregate in any number? How do you identify the next shooter? Where is he going to strike?
The only hope we have is that the young man from Colorado is insane. He HAS to be insane. If those were the actions of a properly thinking mind, then we are all in trouble.
Please, dear God, let him be insane.
