Liberalism is the watchword in cities like New York, but in a part of small-town America racism is still a major cause for concern. In this Correspondent film, reporter Tom Mangold unfolds the story of an undercover cop in Tulia, Texas, who arrested one tenth of the town's black population on alleged narcotics charges. Five cases have already been overturned, others are on appeal, championed by a new campaign by the US Civil Rights movement to seejustice. Producer Eamon Hardy ; Editor Karen O'Connor.
