Reuters reports the FBI interviewed the elder of the two Boston bombing suspects in 2011 at the request of a foreign government.
The man was questioned at Russia's request, according to DEBKAfile, because of his suspected ties to Islamist terrorism in the Caucasus.
CBS News observes:
This is an issue [the FBI has] had in the past. They interviewed Carlos Bledsoe in Little Rock, Ark., before he shot up an Army recruiting station in 2009. They were also looking into Major Hasan Nadal before the Fort Hood shootings.
However, the FBI has maintained in those incidents that they took all the steps they were asked to and were allowed to under the law.Understanding how these men were able to carry out their attacks--even after coming to the attention of federal law enforcement authorities--is critically important. In fact, it is essential if future mass casualty attacks on American soil are to be prevented.
