South Carolina police charged after black man shot dead

A white South Carolina police officer has been charged with murder after video emerged of him shooting a black man running away from him, the BBC reports.
State investigators arrested North Charleston police officer Michael Slager on Tuesday after viewing the mobile phone video of the shooting.
Authorities say victim Walter Lamer Scott was shot after the officer had already targeted him with a stun gun.
The US Department of Justice is set to launch an investigation.
“When you’re wrong, you’re wrong,” North Charleston Mayor Keith Summey said, announcing the arrest. “When you make a bad decision, I don’t care if you’re behind the shield or a citizen on the street, you have to live with that decision.”
The incident on Saturday began after Scott’s car was stopped for having a broken rear light, local media reported.
