Missouri is a Pro-Second Amendment State. Castle Doctrine. Concealed Carry (Permit) as well as open carry is legal. Legal to carry firearms in ones vehicle. These protestors get into the wrong area they may get “protested” back....
If I were a protester I would beeline to the white areas and peacefully protest. In my area that would scare the bejesus out of the old white folk. I would be provocative. And at the first sign of push-back, the Abercrombie and Fitch would go up in smoke. Then a few Starbucks.
But these folks are probably not that bright. They will end up burning down their own blocks.
