Hawthorne, CA police arrest man for videoing them, shoot his dog

Spocko sez, "What are the current rules for filming police in the state of California?

This man seems to believes that he should be arrested for filming the police and offers himself up for arrest after clearly holding his phone up to film them.

He places his dog in his car and is arrested. While handcuffed and being led away, the dog jumps out of the car to go to the man. The police see the dog as attacking them and when it doesn't stop, shoot the dog several times.

Would this had happened if the man (and the police) knew the law about filming police in public in California?"
