Those would be attributed to human error or bad intel. Somebody who happened to develop their own opinions rather than blindly following orders tends to get railroaded as a scapegoat*.
My worry about the Boston bombing is how it will be used to give more power to the government/politicians/bureaucrats/PTB/Banksters.
If I had to wager a guess, it will be used to help ram through the current weapons bills, add new bills to require more documentation on explosive precursors (they'll tack on some language to weaken the 2nd amendment in a backroom deal), and establish a more public presence of the DHS.
All sensible little steps toward the goal of a police state.
