Potomac Institute Fellow Ben Sheppard, PhD, is an expert on political and psychological effects of terrorist attacks. In a radio interview on the Jim Bohannon Show, Dr. Sheppard talks about the "homegrown" terrorist risk highlighted by a recent sting operation in the Washington, DC area.  That operation led to the arrest of a Virginia man, for allegedly participating in what he thought was a plot to bomb Metro transit stations. Click here to listen to Dr. Sheppard's interview on domestic terrorism risks.
