The gun belonged to his friend, who was the person that removed the orange flash-hider. It's hard to know exactly what happened in this incident as many of the news stories have slightly different details. Regardless of timeline, regardless of whether the police actually told him to drop the weapon, regardless of anything; the parents should have known full well that their son, walking around anywhere in Cali with something that looks like a real firearm, could get beaten up, arrested or shot. I for one don't think the parents have anything to blame the police for. The responsibility lay with them and their son for not having the sense to bag that shit toy or not.
