We will never forget the harrowing video footage of Walter Scott's traffic stop, in which the unarmed black South Carolina man was shot in the back by (then) police officer Michael Slager while running away. Walter had been pulled over for a broken tail light.  

A year later, Walter's youngest son, Miles Scott, wants Slager punished to the full extent of the law and requested on Wednesday that U.S. District Judge David Norton give him life in prison, according to ABC News. Slager originally faced murder charges in state court, but those charges were dropped due to a deadlocked jury. Instead, as part of a plea deal, he pleaded guilty to violating Walter's civil rights.

During that first trial, Slager argued that although Scott had his back to him and was 18 feet away from him, the man nevertheless posed a threat because Scott could have turned around and attacked him, CNN reports.

In fact, Slager claims that this happened, and that he and Scott struggled over a taser. According to Slager, Scott, a 50-year-old man, was stronger than him; however, he said he was able to get his taser away from Scott, after which he pulled his gun.

"I knew I was in trouble," Slager said. "I was in total fear Mr. Scott didn't stop, continued to come towards me."

Prosecutors say there is little evidence of a physical struggle.

There is, however, video evidence of the shooting, taken by a bystander, Feidin Santana.

Satana testified in court this week about what he saw, calling the shooting "abuse and something that wasn't necessary."

Slager's team attempted to discredit Santana, questioning his hearing and bringing up his tax returns.

The civil rights charge Slager pleaded guilty to could have him spending the rest of his life in prison. His legal team has asked the judge that the ex-cop be given no more than 13 years. But Scott's son, Miles, told the court why Slager needs to get life.

"I miss my father every day," said Miles. "I would like you to sentence the defendant to the strongest sentence the laws allows because he murdered my one and only father."

A decision on the sentencing is expected soon.
