LOS ANGELES - Investigators will review hundreds of hours of video of an immigration rally where police clashed with the crowd, wielding batons and firing rubber bullets to break up the demonstration, the police chief said Thursday.

Chief William J. Bratton said in an appearance on CBS’s “Early Show” that he was “not happy” when he watched videotape of the events at MacArthur Park late Tuesday, when officers fired 240 nonlethal rounds to clear demonstrators.

He said police and news media video would aid investigations into whether the officers’ tactics were appropriate.

“We have to really try to determine exactly what happened. We’re fortunate in this instance that we have a lot of video to look at,” Bratton said. “We have literally hundreds of hours of video to review to make our decisions.”

News images showed police hitting a television cameraman to the ground, shoving people who were walking away from officers and injuries from the rubber bullets.

Rally organizers denounced the police action as brutal.
