Blame the police all you want or don't blame them. They will continue to both support you and not at the same time because their allegiance is to the jobs and their jobs are to follow orders from those giving them orders.

Focusing on blaming the police is kind of beside the point. The police are nothing more than pawns of the existing government. If the government is your enemy then police will be your enemy. Even if a police officer decides to use his free will and decides to support you, he'll just be fired off the police force then replaced by someone who will follow the government's orders so the end result will be that the police won't support you.

When Trump was President and we all still thought he's win legitimately through legal system we respected, the police were our friends because the law was our friend and thus the government. Today, the government circumvented the law to disenfranchise our vote so they are our enemy and now the police are our enemy.

That's just how it goes. Evidently though, it's the leaders of the police force who are the true enemies. Like in Chess, the pawns might be in your way but it's the King you need to checkmate.
