A federal judge has refused to dismiss civil rights claims over the wrongful shooting death of a disturbed 68-year-old man by White Plains police officers who responded to his apartment after receiving a call from the Life Aid medical alert system.

Kenneth Chamberlain Sr. was on psychiatric medication when he refused to allow the officers to enter his apartment in November 2011. The police entered anyway to confront Chamberlain, who was armed with a knife and making threats.
