LA demonstrations roll on as political tensions ramp up

Street demonstrations in Los Angeles are rolling on as political tensions ramp up. The city's mayor has said LA is being used as a 'test case' for the federal government to take over from local and state authorities. Now more troops are on their way. About 700 marines have been mobilised and the Pentagon has said the US President is deploying another two thousand National Guard Troops to the area after the initial order this weekend. LA correspondent Toni Waterman spoke to Lisa Owen.
