A South Carolina police officer was arrested and charged with murder on Tuesday after a chilling video surfaced showing him shooting an unarmed black man in the back eight times.

Michael T. Slager, 33, says he feared for his life after Walter Scott, 50, grabbed the officer's Taser during a scuffle and then attempted to flee the scene. 
But the graphic video, which was recorded by a bystander and published on The New York Times, shows that Scott had dropped the stun gun at the officer's feet before running away. 

The deadly incident took place in broad daylight last Saturday in North Charleston, South Carolina, where a news conference was held Tuesday. 

Mayor Keith Summey condemned Officer Slager's actions, saying, "When you're wrong, you're wrong...And if you make a bad decision, don't care if you're behind the shield or just a citizen on the street, you have to live by that decision." 

The shooting comes less than one year after two other high profile police murders -- those of Eric Garner in New York and Michael Brown in Missouri -- rattled the nation and sparked a debate over the use of deadly force by police.
