That’s like saying, North Korea is actually not a bad place to live because any sort of semblance of evidence proving so is propaganda. Do you seriously think that black communities would all start singing peaceful campfire songs if the police were removed.
Copaganda is not as simple as “cops are good”. Sometimes, it’s as complex as “Cops are necessary evils in Black communities because without them, said communities would be overrun with crime and violence. See? Look who lives there”
