evidence: Prosecutors have already put supervisory officers on the stand to testify that, even if Chauvin pinning Floyd with his knee fell within policy, doing so for 9 minutes, 29 seconds did not. In their pretrial filing, they said Chauvin and two other officers held their positions for four minutes after Floyd lost consciousness — and two minutes beyond when he no longer had a pulse. [...] One witness testified she saw Chauvin lift his right leg at one point, shifting his full weight onto Floyd’s neck with his left leg. Another said Chauvin never eased up, either by putting a hand on the ground or leaning on a squad car next to him. [...] Nelson has also made clear he will argue that Floyd died because of drugs he had taken, not because of Chauvin’s actions. An autopsy found fentanyl and methamphetamine in Floyd’s system.
