In, 1901, the Manitoba Court of King's Bench described the Mr. Big scenario as ôvile and contemptible,ö yet it remains an accepted interrogation technique. Posing as organized crime figures working for a powerful boss known only as ôMr. Big,ö who is willing to offer incentives but only if the details of any criminal past are disclosed, undercover police officers encourage, cajole, bribe and compel confessions out of key suspects. The scenario is often successful at achieving its goal - a confession - but it is no coincidence, this book charges, that these coerced confessions come most often from within vulnerable populations.
