The solution seems so simple to me. Declare martial law. If you are seen looting, you will be shot on sight. No matter what race you are. If you are seen committing arson, you will be shot on sight. No matter what race you are. If you are seen attacking police, firefighters, or anyone else, you will be shot on sight. No matter what race you are. If you are out after curfew, you will be arrested. No matter what race you are. If you resist arrest, you will be shot on sight. No matter what race you are.
Eventually, we will run out of animals who refuse to live within society's rules. Maybe a small select few of them will wise up. But I kinda doubt it.
