"But Tsarnaev’s alleged turn to violent crime is hardly extraordinary—the particular form of crime he chose is worthy of closer and more nuanced attention than the press seems capable of giving it. No one becomes a jihadist terrorist in a vacuum, any more than one finds oneself in a U.S. Army uniform shooting at Taliban fighters in a vacuum; recruits may have all kinds of personal reasons for signing up, but there’s a pre-existing structure that then welcomes and shapes them and directs their actions toward a larger strategic purpose."

As the interviewing of Muslims connected with the Boston bombers should keep in mind the principle of Taqiyya.
Understanding Taqiyya ― Islamic Principle of Lying for the Sake of Allah
"The word "Taqiyya" literally means: "Concealing, precaution, guarding.” It is employed in disguising one's beliefs, intentions, convictions, ideas, feelings, opinions or strategies. In practical terms it is manifested as dissimulation, lying, deceiving, vexing and confounding with the intention of deflecting attention, foiling or pre-emptive blocking. It is currently employed in fending off and neutralising any criticism of Islam or Muslims."
