Tony Cartalucci: Contractors at Boston Marathon Stood Near Bomb, Left Before Detonation.

What appear to be private contractors, wearing unmarked, matching uniforms, and operating an unmarked SUV, affixed with communication equipment near the finish line of the Boston Marathon shortly after the bomb blast, can be seen beforehand, standing and waiting just meters away from where the first bomb was detonated. The contractor types had moved away from the bomb's location, before it detonated, and could be seen just across the street, using communications equipment, and waiting for similar dressed and equipped individuals, to show up after the blasts. An already widely distributed photo, showing the contractor types on the bottom left, just left of where the bomb was placed and detonated. The men are wearing matching, unmarked uniforms, large black bags, and appear to be waiting, separately, and behind the rest of the crowd. In the upper left corner, a wooden structure forming one half of a temporary photography bridge over the finish line, can be seen and serves as a useful reference, when establishing the contractor types position in other photos. After the explosion, two of the contractors seen by the wall next to the bomb, appear across the street, both using communication equipment. This photo too has been distributed and enlarged many times across the internet. An unmarked SUV with considerable amount of communication gearon the roof appears, surrounded by identically dressed men. The vehicle parks near the bleachers. The men, numbering between 6-8, then begin tearing up the skirting around temporary bleachers erected for the event, opposite the explosion, before taping it off. Then, what an FBI bomb squad truck, pulls up directly behind the contractor types SUV, with a woman clearly wearing the letters FBI on her tactical vest, emerging and speaking with the contractor types. Together, they disappear from the scene, leaving their vehicles behind. What appears to be an FBI bomb squad truck pulls in, with a woman wearing what is clearly the letters FBI on her vest. She talks with two contractors and event staff tore up, is now taped off. The FBI truck and contractor SUV sit seemingly abandoned, neither the FBI agent, nor the contractors can be seen. What they did, or where they went remains so far. It should be noted, that with the exception of the contractor types, all other responders at the scene, including the FBI agent, can be clearly identified, from police to the fire department, to medics, and even individuals wearing vests wit BAA Physician written on them. It should also be noted that no other uniformed individuals can be seen standing near the bomb site from the contractor types.
