The entire nation was united on police reform the day Floyd was killed. That didn't last long, because the rioters showed up. If the riots had been put down right away, we could have had a discussion abour reigning in the police. As it is, reigning them in is not what most people think is necessary right now. They want the opposite. That is on the rioters, arsonists, and other felons having fun every night to Dems can cynically say, "This is Trump's America." People see through this, which is why Trump is rising in the polls.
By the way, I agree we need reform. I have a relative who is a cop, and we had a disagreement one time at a family gathering. My position was that a cop shouldn't fire until they actually see a weapon, not just suspect that a weapon may exist. He said that is opposite of all their training. He said their training is carefully calibrated to allow the cop to return home to his family on any given night. I said, "You aren't the Army. You are the police. The rules of engagement for the military against enemies should be different than the rules of engagement for cops. We expect our police to assume some risk, not push all risk to the citizens." He disagreed. Because he was family, and because of where we were, I let it go. But, I still think cops are too fast to pull the trigger. Of course, all this has nothing to do with so-called "systemic racism," so we will never get true police reform.
