Just to clarify...
The implications are that these rioters are so dumb, they’d implicate themselves before remembering they’re supposed to blame their sworn enemies (if only in their own minds).
It’s kind of like a cop knocking on a door and when the perp answers the door, the cop says: “We’re here to arrest John Doe. Are you John Doe?”
And John Doe answers: “No, officer. I’m not me.”
