“Why is it that most of these claims of out of control police forces come from Cities that are exclusively operated by Liberals? Even the most famous rioting city of Ferguson was forever controlled by Democrats.”
As usual, no evidence provided for this assertion. But for the sake of playing along, it’s probably because liberals tend to want to stop police brutality, whereas Conservatives cities tend to applaud it and encourage it.
And in the case of some police officers, literally applaud it, as seen in this article which I’m sure you didn’t read.
