This Fifth Estate documentary raises questions about whether the investigation into the Mayerthorpe police killings, including the arrests of two Alberta men, is aimed at distracting attention away from allegations of negligence within the force. Bad Day at Barrhead examines the years following the March 3, 2005, shooting deaths of RCMP officers Const. Anthony Gordon, Const. Lionide (Leo) Johnston, Const. Brock Myrol and Const. Peter Schiemann at a rural farm in Mayerthorpe, Alta. Shooter James Roszko died at the scene and, last July, police announced they had arrested two men from a neighbouring town in connection with the killings. Dennis Cheeseman, 23, and Shawn Hennessey, 28, each face four counts of first-degree murder in the deaths of constables Brock Myrol, Peter Schiemann, Anthony Gordon and Leo Johnston.
