Arson at Wal-Mart?

This happened yesterday at the Wal-Mart in Brea, CA, just a mile or two from my home in Fullerton. I may be jumping the gun here, but I wouldn't be surprised if this turns out to be some kind of unionist wacko of the "Wal-Mart is the antichrist" set. I sure hope they can identify the perpretrator from the video and catch the coulda-been-a-murderer. I'm already having visions of a Law & Order- or CSI-type interrogation room confession where the arsonist tearfully says, "I never meant to hurt anyone, I just wanted to teach them a lesson!"
