Yep. And back in the days of the USSR, the Kremlin would rant about how racist Jim Crow was. The North Vietnamese dropped leaflets on US bases encouraging black soldiers to defect because the US government was using them as cannon fodder.
This was propaganda and it was also true.
If China and Russia are spreading propaganda about police brutality in the US, the solution isn't to silence criticism of the police. The solution is to reform the goddamn police.
Those of us terrorized by the police for generations don't need propaganda to tell us who the police are. Your statement just reveals the wonderful position of privilege you enjoy in the system.
citizen vs police is the the police forces' favorite way to divide people. that's why "the thin blue line" is a thing. citizens are enemy forces for them.
