CONCORD — A police brutality trial involving four Manchester police officers starts Tuesday in federal court in Concord, despite their lawyers’ fears that the death of Tyre Nichols will hurt their chances for a fair trial.

Last week, U.S. District Court Judge Paul Barbadoro rejected requests from three of the four officers to postpone the trial.
