The federal trial for three former Minneapolis police officers charged with violating George Floyd’s civil rights as Derek Chauvin pinned the Black man’s neck to the street is expected to begin Monday with opening statements, after a jury of 18 people was swiftly picked last week.

J. Kueng, Thomas Lane, and Tou Thao are broadly charged with depriving Floyd of his civil rights while acting under government authority. All three are charged for failing to provide Floyd with medical care and Thao and Kueng face an additional count for failing to stop Chauvin, who was convicted of murder and manslaughter in state court last year.

Legal experts say prosecutors have to prove Kueng, Lane, and Thao willfully violated Floyd’s constitutional rights, while defense attorneys are likely to blame Chauvin for Floyd’s murder, which was videotaped and triggered worldwide protests, violence, and a reexamination of racism and policing.
