Again, what are the chances of a doppelganger of the Washington Navy Yard tragedy perpetrator being in a photo of such narrow scope with the "Tsarnaevs" at Boston??

Minute to infinitesimal!!!

We must admit the very real likelihood that TPTB are mocking us, and letting on to us that they know we know.

Scary development, because it also means they don't care, and (very likely) that time is very short.
