You don't call the police department you call the mayor's office and you give them a piece of your mind. I sure as Hell am going to:

Whittier City Hall
13230 Penn Street
Whittier, CA 90602
Main Telephone: 562-945-8200
Fax: 562-464-3572

Don't call Whitter ...

it was in La Habra!

down the road from Whitter (LA Co.)

La Habra is in Orange Co.

Someone correct me if I'm wrong, but this happened in La Habra, not in Whittier (or as charmingly referred to by the OP, Wittier). Since they're two separate cities, complaining to Whittier won't do much good.

Is there any sort of chance that the cops or someone they know did this pretending to be protesters? That would explain why they weren't arrested. Maybe they're just being agent provocateurs.
