Little Rock, 1957. Now it's the blacks writing on the walls and attacking the police.
IIRC it was Federal Marshals protecting the students because the police controlled by the local Democrats could not be relied on. Remember that all the segregated southern states of the time were controlled by Democrats. Just to name a few: George Wallace, Lester Maddox, and of course Bull Conner who was on the Democrat National Committee. But it's Republicans who are racist.
