You have very senior level "former" CIA and FBI officials whoring out as spokespeople for the likes of Al Jazeera talking about how it "could be domestic terrorism" and now shit is getting hushed up because someone makes phone calls to push the investigation one way instead of another, and the Boston Police (who are normally pretty capable) just got sidelined in favor of the FBI taking over. Smells like an official cleaning job but I seriously doubt that all of the .gov players will be going along with it. There is just no way to suppress all of that camera footage which we know is out there.
