In Berkeley about midnight tonight a line of unmarked white vans, SUVs and large sedan equipped with flashing red and blue lights moved across Bowditch adjacent to the First Church of Christ Scientist and People's Park, turning down Channing to park in the block between Bowditch and Telegraph.

At about 12:30 a group of demonstrators was contained on Telegraph at Channing between two lines of police in riot gear, with additional police lines a block away in either direction.

It seems very likely that mass arrests are imminent, and these vehicles have been assembled to transport arrested persons. 

A live stream that appeared to be coming from outside the line of police at Dwight showed a crowd of observers who looked like most of them were young, student-age white people. Some were taunting the police, with occasional chants of "Hands up, don't shoot" accompanied by upraised hands.
