That douchbag, like all of them, knows whatever he puts out there can't be unlearned. It's like cussing in front of a child or a parrot or a lawyer blurting out some unproven claim about a defendent, knowing it will influence the jury even though the judge orders the jurers to ignore what was just said.
Planting it in their brains it's ok and right to shoot dissidents that don't go along with the Left's agenda was the main lesson he was teaching that day.
