That’s not accurate.
The person shot and killed (Mr. Ah-loo) was unarmed. He was struck by a round fired at someone (mr. Gamboa) who had snuck out of the protest and returned with an AR-15.
Gamboa was arrested for attempted murder, and the person who fired the shot is/was being investigated, but has not been arrested/charged at this time
Gamboa snuck away, retrieved a hidden gun, came back and pointed out at someone. He very clearly had ill intentions, and was arrested for attempted murder.
