Day six of the Tyre Nichols trial saw the defense continue its efforts to justify the force used on Nichols by former Memphis police officers.

A police training expert testifying Saturday as a defense witness in the trial of three former Memphis officers charged in the fatal beating of Tyre Nichols acknowledged that kicks and punches to Nichols' head were unnecessary and excessive.

Memphis police officers are facing state charges including second-degree murder and aggravated assault in the beating death of Tyre Nichols.
