A Facebook Live video shows a man and woman later discovered to have overdosed on heroin lying unconscious on a Memphis, Tennessee, sidewalk as a crowd of people mocks and films them.

Courtland Garner is defending the video posted on his Facebook page and viewed nearly 3 million times. At one point in the video, Garner puts his phone inches from the woman's face. He and others in the crowd can be heard laughing at the pair.

Garner says he shared the video to encourage people not to do drugs.

Memphis Police Officer Louis Brownlee says the 59-year-old woman and her 60-year-old husband admitted to snorting heroin before the video was shot. He says the couple was hospitalized and survived. The woman was taken into custody on an outstanding warrant.
