Maybe so...
So let me ax you, what do they, all the followers, do when the one in the front begins to sprint across the lawn, and in an in instant there's a POW!! and they all get the first guy's brains splattered all over them?
That’s exactly what the instigators want.
Crowd runs in all directions, more brains pop, thousands injured, Trump accused of being a murderous dictator murdering peaceful protestors by proxy, major societal fallout until he resigns/impeached.
As planned.
