Charleston, South Carolina (CNN)A prosecutor vowed Monday to retry a white former police officer charged with killing an unarmed black motorist in North Charleston, South Carolina, after the jury failed to reach a verdict following 22 hours of deliberation.The judge declared a mistrial on the fourth day of deliberations in the murder trial of Michael Slager, the former North Charleston officer. 

"We will try Michael Slager again," 9th Judicial Circuit Solicitor Scarlett A. Wilson said in a statement expressing disappointment that Slager was not convicted in the five-week murder case in state court.Slager shot and killed Walter Scott, 50, after an April 4, 2015, traffic stop. The shooting was captured on a bystander's cell phone video, which showed Scott running away as Slager fired eight times, striking Scott three times in the back.The jurors -- 11 whites and one African-American -- struggled to reach a consensus. They returned to deliberate three times Friday after indicating they were deadlocked. One juror, in a note, said he couldn't vote for a conviction and wouldn't change his mind. Monday brought a slew of questions, such as requests for clarifications on terminology related to the law, before the mistrial was declared.
I think anyone who saw the video will understand how much of a travesty this is.....
