FERGUSON, Mo. (AP) — The Rev. Jesse Jackson has joined protesters marching in the streets of a St. Louis suburb following the shooting death of an unarmed black teenager by a police officer.

Jackson linked arms with other protesters Friday evening as they walked through the streets to the site where 18-year-old Michael Brown was fatally shot last Saturday while walking in a street. The prominent civil rights activist bent over in front of a memorial cross and candles and let out a deep sigh.

He led the protesters in prayer and urged them to “turn pain into power” while fighting back non-violently without self-destructing.

Police and protesters clashed violently for four nights following the shooting but have remained peaceful since the state Highway Patrol took over security Thursday and pulled back armored vehicles.
