Orlando Police Department's Active Reserve Unit is made up of 37 retired officers who pick up shifts to plug staffing gaps. Records show at least five of them have been arrested, accused of crimes including possessing a short-barreled shotgun, stalking, grand theft and vehicle title fraud. At least three of those five were disciplined by the agency for breaking the law; another stood trial twice for tasing a suspect who was handcuffed to a hospital bed, but avoided conviction or discipline.
