Video: Police Officer arrested after video showed him shooting an unarmed black man in the back.

A white South Carolina police officer was arrested Tuesday after video showed him fatally shooting a fleeing, unarmed black man in the back.North Charleston Police Officer Michael T. Slager, 33, can be seen shooting 50-year-old Walter Scott after a confrontation on Saturday, according to The Post and Courier. Slager chases Scott and shoots at him eight times in the video recorded by a passerby and obtained by The New York Times.

Scott was later pronounced dead.

The graphic video raises questions about Slager's original assertion that he used his gun because he felt endangered.

The confrontation started when Slager had reportedly pulled over Scott because of a broken taillight. It escalated into a foot chase as Scott allegedly fled because there were family court-issued warrants for his arrest. Slager pursued Scott into a grassy lot and claimed that he fired his Taser to subdue him.

Moments later, Slager reported on his radio, “Shots fired and the subject is down. He took my Taser,”

Earlier this week, an attorney for Slager said the cop felt threatened after Scott tried to overpower him and took his Taser. Today that attorney told The Post and Courier that he's "no longer involved" in the case.

But first images in the video are of Slager shooting at Scott as he runs away from him. It also appears that Slager drops the Taser near Scott after he was gunned down.

The shooting in North Charleston comes on the heels of several high-profile cases of police officers using deadly forced against unarmed black men in Ferguson, Missouri, Cleveland and New York.
