that's because when the police kill people, there are no repercussions for them, no matter how much obvious bias, incompetence, disregard for human life, and malice is apparent in their activity. police can literally murder people on a whim and 99% of the time not even be suspected of any crime much less prosecuted. The George Floyd murder required that it was videoed from start to finish for there to be any chance of an actual criminal trial proceeding. All of the police murders that we hear about now are all news because there is now video. Think of all the decades and decades when there was no video, how many people must have been murdered on a whim, without the event even being considered a crime. But even today, obviously immensely negligent acts, such as the murders of Tamir Rice and Eric Garner, still basically have zero repercussions for their killers.
This is nothing like the usual "murder rate", where the violence that occurs between people who are not cops is all considered to be crime, and is handled as such. There's no disagreement on what justice looks like. Murder is bad, but aribtrary murder by state actors with no accountability is worse.

please review the accounts of Uvalde as children and teachers were murdered over an hour while heavily armed and armored police stood around and did nothing but prevent anyone else from being able to help. There are many ordinary jobs that are statistically much more dangerous than that of the police including things like roofing, truck driving, construction (source: OSHA https://www.invictuslawpc.com/most-dangerous-jobs-osha/)
