Without changes to qualified immunity, it has no teeth. There are tons of rules already. Eric Garner was killed by a chokehold already banned by the NYPD. Breonna Taylor's killers still haven't even been fired let alone charged with murder or even filing a false police report! (The report said there was no forced entry and Taylor had no injuries.) Her boyfriend WAS arrested though. Federal reduction of qualified immunity to reasonable levels or no deal! Murder is murder.
