During New York’s ’80s and ’90s crack epedemic, a flashy detective who “imagined himself a crusader who created his own rules” and his star witness, a crack addicted prostitute who seemed to constantly be at the scene of homicides, sent dozens of men to prison for life. Now, they are under investigation.
