There IS a double standard:
Black rioters had robust, national backing from professional Grievance Mongers, the Prez, the national media, and the US Justice Dept. Accordingly, they were left free to wander screaming, given “Space to Destroy”. Virtually NONE were shot while they were on their rampage of destruction.
Meanwhile:
The bikers had no media or Gummint allies, had no immense propaganda machine backing them up. Accordingly, the police felt they had a free hand and shot them down. SWAT team members armed with military rifles equipped with optical sites shot them in the head and neck.
They didn’t have a chance, and no quarter was given.
Said Grievance Mongers have been pushing a narrative in social media that unlike in Ferguson, etc., there were NO "mass arrests" in Waco - because the perps were white. When someone points out the 170+ arrests and seizure of all related motorcycles, various criminal charges filed - you know, the actual facts of the case, they ignore the information or claim it is misdirection provided by the "right-wing media".
I truly wonder what color the sky is on their world.
