I'm not really sure what this accomplishes. If they're trying to get these outlaw biker gangs to stop committing crimes, why not...you know...arrest them and keep them in prison? Hell, strap 'em to the chair. That'll fix 'em. But it seems silly to ban their (checks notes) tattoos. You're just hiding the visible identifiers, not eliminating the behavior.
But I feel good that the US doesn't have the stupidest government as long as Australia is around.
