A man arrested in the 2010 shooting death of an unarmed Columbia teen will not be tried for murder.

The State newspaper reports that a judge has filed an order stating that 33-year-old Shannon Scott reasonably believed his life was in danger and will not be prosecuted, in accordance with South Carolina's “Stand Your Ground” law.

Scott was arrested in April 2010 and charged with murder in the death of 17-year-old Darrell Niles, who was shot to death in his car.

Shortly before the shooting, an SUV filled with young people who had threatened Scott's teenage daughter drove by his house and fired shots.

Authorities say Scott then saw Niles' car and, believing it was part of the threat to his family, fired a gun from his front yard, fatally shooting Niles in the head.

Solicitor Dan Johnson has appealed the ruling to the state Supreme Court.

As the newspaper reports, a key legal issue in the case is whether the state’s 2006 “Stand Your Ground” law will protect those who may legitimately fear for their life but also unintentionally kill bystanders.
