I can tell you as a person who studied the civil rights movement, whose still living parents grew up in the Jim Crow South and who personal knew some of the secondary people who made the history books during that time (I am 51), “the left” or at least a large part of never trusted any law enforcement.
From my perspective, the American progressive left is deeply distrustful of local / state police, but are more inclined to believe the feds good at least insofar as they enforce good progressive laws against backwards locals. The feds enforcing desegregation is perhaps the root origin of this sentiment. The conservative right on the other hand is very inclined to support local police, but have hated feds with notable intensity, probably sharing the same root but really intensified in the 90s.
