Details have emerged of testimony given by Darren Wilson, the Ferguson police officer who fatally shot the unarmed teenager Michael Brown. According to The New York Times, Wilson has told authorities he feared for his life in the confrontation that followed him stopping Brown and a friend for jaywalking. Wilson claims Brown reached for his gun during a physical altercation as Wilson was still inside his vehicle. Ballistic tests confirm two shots were fired inside the car, one of them hitting Brown’s arm. It’s unclear why Wilson then fired the fatal shots at Brown after he emerged from his vehicle. Witness accounts say Brown had his hands up and was trying to surrender when he was shot dead. According to federal officials, there is not enough evidence to indict Wilson on civil rights charges in the Justice Department’s probe of the shooting.
