Witnesses say Bales came with a kill squad backing him

We're getting shocking first-hand accounts from survivors of a massacre that left 17 Afghan civilians dead.
Staff Sergeant Robert Bales is accused of the horrid slayings. But survivors swear he was *not acting alone.
Witnesses say there were many Americans with lights on their heads and guns as they tore through their village, murdering friends and family where they stood. They estimate there were at least 15 to 20 more soldiers.
Since the beginning..Afghan president Hamid Karzai has believed other American soldiers were involved.
The Pentagon is adamant Bales was alone.
