The feds were well aware of the planned Boston Marathon bombing. How else did they have their "crisis actors" there in 5 minutes. Within 5 minutes of the bombing the news media was interviewing a woman who seemed to fully understand the situation and had perfect answers for every question. That was odd but the same woman was interviewed days later when they caught up with the brothers in the suburbs and once again she had every answer down pat. I believe they were aware of the brothers, their plans and they let them execute their plans to create another false flag event.
