There's more than a few unanswered questions about the Boston Bombing, and none of them were answered in the trial of Dzhokhar Tsarnaev.
How did a "terror attack" that approximated the damage of a bad car accident instantly lead to a shock and awe siege of Boston? More went on in Boston than meets the eye, and DT is the fall-guy.
His conviction and subsequent death penalty are erroneously assumed to provide "closure."
Instead, it will provoke more people to ask more questions.
For starters, how did these guys who were on FBI/CIA/FSA radar manage to pull this off?
And how did their terror attack happen to coincide with a FBI/CIA/FSA anti-terror exercise?
You can't make these questions go away just by hanging Tsarnaev.
