Facebook is facing criticism for not removing quickly enough a shocking and graphic video of a man killing a 74-year-old grandfather in Cleveland. The alleged shooter, Steve Stephens, posted the video of himself shooting and killing Robert Godwin Sr. as the grandfather was picking up aluminum cans on Sunday afternoon. It appears Stephens picked the man at random. A manhunt is underway to find Stephens. The video is among a series of shocking videos of rapes, suicides and incidents of torture that have been live streamed or posted on Facebook.
