I remember seeing this when it originally aired ("Mr. Big" sting):
http://www.cbc.ca/fifth/2008-2009/co...age/video.html
In an exclusive interview, the fifth estate's Linden MacIntyre talks to one of the men recently convicted and sentenced in the deaths of four Mounties at Mayerthorpe, Alberta in March 2005. Shawn Hennessey's story has never been fully told, until now. On the eve of his plea to manslaughter charges, Hennessey sat down to talk to MacIntyre about the events leading to that fateful day, about James Roszko, and his own role in the tragic event.
