NORTH CHARLESTON, S.C. — The video of a North Charleston police officer shooting an unarmed man in the back will now cost news outlets that want to run it $10,000, according to a publicist representing the man who shot it.

Cease-and-desist letters went out this week to news outlets around the world from Markson Sparks, a publicity and celebrity management company based in Sydney, Australia.

The video, taken April 4, showed a North Charleston police officer, Michael T. Slager, shooting a man who ran from him after a traffic stop. A bystander, Feidin Santana, took the video and then turned it over to the family of the man who was killed, Walter L. Scott.

The officer was charged with murder and remains jailed. The video, viewed more than one million times on YouTube alone, quickly came to represent the excessive use of force by the police.
