Wow, this just simply amazes me, and in CA no less, the birthplace of this nation's modern protest movements. Reminds me of police actions before the Watts riots and during the VN War protests. How do these LEOs come off thinking this is acceptable behavior? Please don't give me the "they're just doing their job" excuse. Beating up on unarmed, non-threatening, barely-past-pubescence young adults is not "doing their job" IMO. Very, very sad...
Follow the cop that started it, the second one from the left, helmet #114 (it appears to read - can't really make it out). He's the only one who goes on non-stop beating through the whole video. It's as if he actually enjoys this form of employment...
