"A suicide bomber driving a taxi set off his explosives near a convoy of United States civilian contractors and accompanying soldiers here Saturday morning, killing himself and four bystanders, the Kabul police said. One of his intended targets was wounded. Within hours, American soldiers fired into a crowd of Afghans near the scene of the blast, killing one man and wounding another, according to a United States military spokesman, Lt. Col. David A. Accetta. “It was an unfortunate incident, and we are investigating the cause of the accidental discharge of a weapon,” he said."" Let me save you time. The US military investigation will conclude that US soldiers were justified in shooting at civilians.
