He just admitted to murder.
This is California “murder” requires premeditated actions and a depraved mind. Unintentional homicide, intentional homicide,or negligent homicide would be the max charges that any DA could hope for. There is precedence with actors shooting and killing another actor or set member the most recent and high profile was Brandon Lee during the filming of the Crow. The actor who fully pointed a loaded 44 caliber weapon with a live round in it and shot him dead was never charged for it because actors are not typically in the safety chain protocols for on set cold weapons. Regardless what the internet blowhards say this is sound legally verifiable precedence in the same legal jurisdiction of California no less.
