Thoughts on the Colorado shootings
Truth About Guns shows a sign the theater posted, "NO FIREARMS ALLOWED". For some reason, the shooter didn't follow that. The Washington Times notes that there was an early attempted mass shooting in the city, which ended when someone shot back.
And Don Kates sends an email: "it turns out that Century 16 Theaters no-gun policy also applies to its own security personnel, including the off-duty policy officer on the premises.
UPDATE: link fixed, thanks!
Hence, the reality here is that CO concealed carry laws were irrelevant since there was zero firearms-backed security in the theaters, no one could have a gun on the premises, and the area, like Columbine, was a completely open and non-defended free-fire zone for any assailant. The law-abiding followed the rules."
