I have had interactions with police in both russia and US (I am not white). It is not even close.
Police in the US clearly do a lot of very bad, brutal things, but they still have a measure of self-control.
Russian police are literally more like open criminals without any sort of accountability (outside of targetting say the son of a well connected government thug or oligarch by mistake). Russian police are completely unhinged.
Have you ever dealt with russian police? And if yes, in what context? What is your russian like, what level is it?
Keep in mind I explicitly said that US police are brutal.
