Today marks the one-year anniversary of the killing of Kenneth Chamberlain Sr., an African-American Marine veteran in White Plains, New York, shot dead by police in his own home. On November 19, 2011, White Plains police officer Anthony Carelli shot Chamberlain inside his apartment after police responded to a false alarm from Chamberlain’s medical alert pendant. Despite Chamberlain’s insistence he was alright, police broke down his door, tasered him and shot him dead. One officer was heard on a recording calling Chamberlain a racial slur. The Chamberlain family has filed a wrongful death suit against a number of defendants, including the city of White Plains and Officer Carelli. On Saturday, Chamberlain’s relatives joined with the NAACP and other supporters for a march on the White Plains Police Department demanding justice in the case.
