No one should like Floyd. His rap sheet clearly indicates he was an asshole.
In the incident however, the police behavior was against policy and procedure, although under normal circumstances it would not have resulted in death. The misconduct was also probably not racially motivated. The officer involve probably actually knew Floyd, as the worked as bouncers at the same bar. He probably knew Floyd as an asshole from personal experience, and abused his position in the moment to "teach him a lesson." It's very messy as there are no "good guys" in the situation.
