"Protestors were given three warnings by U.S. Park police..." (that's a quote from an online news source)
The night before the U.S. Secret Service were alarmed enough by the riot near the White House that they escorted the First Family to the bunker.
Of course, we all know that ALL the protestors are peaceful. All that looting and burning and attacks on innocent people, the shooting of a black police officer, other attacks on officers, the violence...ALL OF IT is the concoction of FOX News. None of it has actually happened. Bet you didn't know that, did ya!
