POTUS was trying to make peaceful protestors think about what they were doing and not follow instigators to the slaughter. The entire point was agitators breaching the fence, letting peaceful protestors run in, and watching them be slaughtered on the lawn.
That was the point. That was why dc mayor wouldn’t reinforce SS and why dc mayor wants the fence to go down. All for msn to get a shot of dead protestors on the lawn.
