From Executive Producer Morgan Freeman. The Killing of Kenneth Chamberlain tells the true story of the final hours of the life of Kenneth Chamberlain Sr., an elderly African American veteran with bipolar disorder, who was killed during a conflict with police officers who were sent to his home to check on him, when his medical alert device was mistakenly activated. Despite Chamberlain informing the officers there was a mistake and he did not have an emergency, they were recorded taunting him, ridiculing his military service, howling racial epithets at him, and finally, the officers broke his door down.
