They don't feel these guys are a threat…
They probably didn't feel like any of the other Afghan soldiers that killed American soldiers were threat either until the event occurred…

The Massachusetts National Guard reported that the three were reported missing by security personnel at Joint Base Cape Cod late Saturday. A statement identified the soldiers as Maj. Jan Mohammad Arash, 48, Cpt. Mohammad Nasir Askarzada, 18, and Cpt. Noorullah Aminyar, 20.
Pentagon officials who spoke to Fox News say they do not feel that the missing soldiers pose a public threat.
