Despite the presumption of innocence and the right to a fair trial, there are still cases in Canada in which innocent people are convicted — most disturbingly, for murder. The Fifth Estate investigates the murder convictions of four Manitoba men and the Crown prosecutor, George Dangerfield, who presided over all of them. In the 1980s, as Manitoba’s star Crown prosecutor, Dangerfield was legendary for his creativity and flair in the courtroom and his apparent disdain for defence lawyers. He was successful in getting convictions for some of the most notorious murder cases in the province. But, two of those convictions have been overturned, charges quashed on a third, and a federal review of a fourth is ongoing, making Dangerfield responsible for the most wrongful murder convictions in Canada. In The Wrong Man, reporter Bob McKeown looks back on the cases of Thomas Sophonow, James Driskell and Kyle Unger, and he reveals a possible fourth — Frank Ostrowski.
