Thats from the "Connections" series. They caught him off guard, and basically bombarded him with questions. There's a story in the James Dubro book, Mob Rule. Where they tried to do that once outside one of his social clubs and had guys with camera's and mics hiding in a van outside. Cotroni basically lured the interviewer into the club without his camera crew, and the author explains that the host saw a bunch of shadowy figures and they were all Cotroni soldiers, they basically surrounded the guy under Cotroni's orders, chased him out the club and had the film crew scared to move the van because the guys knew they were inside. Funny shit.
i believe that story youre refering to is actually about the commissos in toronto. Remo Commisso at the casa commisso which was on keele st. near either lawrence or st. clair.
