Should they have provided some unarmed rent-a-cop to come in and give James Holmes a severe frowning?

(In Droopy Dog voice:) "Yes, sir. I'll sit down now. Sorry."
That’s kind of the point. It is not financially possible to provide adequate security (two security guards per patron), so if people want to deprive others of their right to defend themselves, they either need to provide perfect security or face bankruptcy and ruin. Or they could, you know, change their minds and allow people to choose for themselves.
