Allegation: Inmate at Roanoke, Va. prison trips. Officers who were escorting him (handcuffed and in leg irons) pull his hair and slam his head into the concrete. Prison admin: No need to check the video. The officers say that’s not what happened. District court: The inmate filed suit too late. Case dismissed. Fourth Circuit: Not so. The statute of limitations started running when the inmate exhausted the prison’s internal review process. If it had started running at the time of the alleged beating (as the district court found), prison officials would have had a perverse incentive to stall their internal reviews.
