Conflicting images have emerged of a Bangladesh native arrested in a FBI sting this week. Authorities say he tried to blow up the Federal Reserve Bank in New York with what he thought was a 1,000-pound car bomb.

His family members were shocked. They describe Quazi Nafis, a Manhattan bus boy, as "timid" and "victim of a conspiracy."

Col. Douglas Macgregor (U.S. Army, retired) discussed that and other topics on Capital Insider.
