In January 2015, Butler was briefly detained after a bar brawl in Death Valley, California and charged with misdemeanor assault, public intoxication and vandalism. He was released following detoxification and a citation. In 2016 he opened up about the event: "This guy started mouthing off about something. He was, like, some drunken Nazi bloke. He [...] started going on about Jews and everything - Jews this, Jews that. My missus is Jewish and I'd just had enough, and me hand sort of met his chin. I whacked him one."
