This 2012 New York Times article details the story of Kenneth Chamberlain Sr.’s death by the hands of White Plains police in 2011. The WCPR was created to hold those officers, and any other officer suspected of police brutality, legally accountable.
From The New York Times:
It was 5:25 on a chill November morning. The officers banged loud and hard, demanding that her 68-year-old uncle open his door.
“He was begging them to leave him alone,” she recalls. “He sounded scared.” She pulls her shawl about her shoulders and her voice cracks; she is speaking for the first time about what she saw. “I heard my uncle yelling, ‘Officers, officers, why do you have your guns out?'”
The string of events that night sounds prosaic, a who-cares accumulation of little mistakes and misapprehensions. Cumulatively, though, it is like tumbling down the stairs. Somehow the uncle, Kenneth Chamberlain Sr., a former Marine who had heart problems and wheezed if he walked more than 40 feet, triggered his medical alert system pendant. The system operator came on the loudspeaker in his one-bedroom apartment, asking: “Mr. Chamberlain, are you O.K.?” All of this is recorded.
The police fired electric charges from Tasers, and beanbags from shotguns [at Mr. Chamberlain]. Then they said they saw Mr. Chamberlain grab a knife, and an officer fired his handgun.
