MORE CRUSHING OF DISSENT: HERE’S AN A.P. PHOTOGRAPH of an antiwar protester assaulting a pro-liberation protester at UCLA.

This was reported earlier at The Volokh Conspiracy, which advises people to take video cameras to protests to document this sort of thing.

Good advice. Video cameras are cheap, and compact nowadays, and you can’t count on there being an A.P. photographer around all the time. I suspect, too, that the mere presence of cameras encourages better behavior.
