This recent interview with Chief Deputy Kevin Murphy (formerly chief of police in Montgomery, AL) begins at 30:58 minutes into the program.
It is an interview that every police officer in America should view and then deeply discuss because it provides a way forward.

Who’s responsibility is it to understand our history? Blacks or white police officers? Knowing there is tension in every inter-racial police contact should help police in their efforts to rebuild trust.
It is ironic that it is a white southern police officer who figures this out. And, at the time, John Lewis and other Freedom Riders were assaulted by police in Montgomery in 1961, a time when Chief Murphy had yet to be born!
Now see Murphy’s powerful 2013 apology to Congressman John Lewis — and let’s begin the discussion.
