UPDATE (4:34 p.m.): Murray has been released on $75,000 bail.
Conrad Murray already entered his plea in the court of public opinion. Today, he reiterated his claim of innocence in a more official forum.
Just hours after he was formally charged with involuntary manslaughter in Michael Jackson's death, and in front of many Jackson family members, the physician pleaded not guilty to the misdemeanor count that could land him up to four years in prison, if convicted.
The long-awaited arraignment took place at the Airport Branch of Los Angeles Superior Court around 2 p.m.—about 45 minutes after Murray arrived to screams of "murderer" and "justice for Michael" from Jackson fans, many sporting red, sequined armbands.
