The Washington Post exposes police misconduct in Prince George's County in two related series. "False confessions" reveals that the county's homicide detectives have used "such coercive interrogation tactics that innocent people have confessed to murder." Depriving the suspects from sleep, interrogating them for days and not allowing them to talk to lawyers are the most common tactics. "Blue Wall of Silence" reports on a decade-long pattern of police shootings. The stories reveal that, since 1990 the county police officers have shot 122 people, killing 47 of them. "They killed more people than any other major city or county police force from 1990 to 2000," the Post reports. Many of the victims were unarmed and innocent. The investigation finds that police officers have rarely - if ever - been disciplined, and that some of their crimes did not emerge until the victims or their families sued.
