The federal trial against three former Memphis police officers charged with the fatal beating of Tyre Nichols has commenced, with opening arguments taking place and jury selection underway. Testimony has revealed that an ex-officer admitted to beating Nichols, describing him as 'helpless' and stating that he lied about the incident. Prosecutors claim the officers employed excessive force as a form of 'run tax' after Nichols attempted to flee, while video evidence contradicts the officers' reports, which omitted key details of the assault. Former colleagues have begun to testify against each other, with one officer describing feelings of anger and a desire for revenge during the encounter. The trial has drawn significant attention, with Nichols' parents speaking out ahead of proceedings.
