A very disturbing video has been released about the Boston Marathon bombing, putting forward the theory the FBI is not telling the public the truth about what really transpired that day, leaving 3 people dead and 260 other injured. Watch the video and form your own opinions on the matter. 

The eye opening clip by Storm Clouds Gathering  is summarized as, "In this video we are going to demonstrate that at the very minimum the authorities had prior knowledge of the attack and allowed it to happen, and this is only the tip of the iceberg."
