Here is Dave Lindorf's very wise, balanced and intelligent assessment of the kinds of evidence surrounding the Tsarnaev brothers, which any responsible crime investigator would feel compelled to follow.I've decided not to quote at length from the article or comment, but just provide the link for any who are interested.

I've also included a link to his fine piece examining the evidence of private military contractors working the Boston event.
Tsarnaev Brothers had a CIA connection.
Why Such secrecy about Private Military Contractors's Men Working the Event.
