Michael Jackson's family have said they are "angry" that his doctor has not faced a more serious charge over his role in the star's death. Conrad Murray faced angry fans when he arrived at a Los Angeles court, where he pleaded not guilty to involuntary manslaughter. A cocktail of drugs were found in Jackson's body after he died at home last June. Dr Murray was given bail and is due to appear again in court on 5th April. Sky News' Greg Milam reports
