Here’s A News Report We’d Be Reading If Walter Scott’s Killing Wasn’t On Video

A North Charleston police officer was forced to use his service weapon Saturday during a scuffle with a suspect who tried to overpower him and seize the officer’s Taser, authorities said.

The man, who has a history of violence and a long arrest record, died on the scene as a result of the encounter, despite officers performing CPR and delivering first aid, according to police reports.

[…]

The incident occurred behind a pawn shop on Craig Street and Remount Road. Slager initially pulled Scott over for a broken taillight. During the stop, police and witnesses say Scott fled the vehicle on foot. When Slager caught up with him a short distance from the street, Scott reportedly attempted to overpower Slager. Police say that during the struggle, the man gained control of the Taser and attempted to use it against the officer.

It was during that scuffle that the officer fired his service weapon, fatally wounding Scott.

“Shots fired, and the subject is down. He took my Taser,” Slager radioed immediately following the shooting.
