LOS ANGELES (AP) - Police Chief William J. Bratton said Wednesday that some of the police tactics used to clear immigration protesters from a park were inappropriate, as news videos showed officers striking people with batons and firing rubber bullets into crowds that included children. Images showed police hitting a television cameraman to the ground and shoving people who were walking away from officers at Tuesday's demonstration. Some injured people were seen in the videos, including a Hispanic man with a bleeding welt on his stomach and back.
