If Farrakhan didn't feel some vulnerability, he wouldn't have had a full blown news conference within hours of Muhammed and Malvo being taken into custody. I'm not saying he knew who the shooters were beforehand - I'm saying he is now doing damage control by getting out in front of the story. Farrakhan may have even been trying to send signals to them during his news conference.
One of the critical leads in the case came from the U.K. ~ RLK
UK ? What was that about?
-----------------------------------
The Brits found out about the terrorist training center in Alabama. That lead to investigations of a holdup and killing in which Muhammad played a part, which then led to Marland/Virginia.
