Another African-American man was gunned down by police, and no one was charged. This time the whole event was recorded

"My name is Kenneth Chamberlain. This is my sworn testimony. White Plains police are going to come in here and kill me." And that's just what they did.

In the early hours of Saturday 19 November, 2011, US marine veteran Kenneth Chamberlain Sr accidentally hit his LifeAid medical-alert pendant, presumably while sleeping. The 68-year-old retired corrections officer had a heart condition, but wasn't in need of help that dawn.
