A number of agencies run training programs in which amputees working as crisis actors have a prosthesis afixed to resemble a bone as a remaining piece of a leg or arm. Casey examines the Boston event by timeline. First the crisis actors are assembled. Then the prosthesis is attached. Then the blood appears.
Notice the photo of Miracle Man laying on his side clutching the back of his left thigh with a straight line sticking out from what appears to be below his knee. This does not resemble a leg bone. Moreover, a person with an injury this severe would not be conscious, and certainly he would not be ignored while aid workers attended to those with lesser injuries. Note also the bright red color of what is pretending to be blood. Many surgeons and trauma medical personnel have testified that blood spilled in injuries is dark red.
[Editor's note: For those who would benefit from an introduction to the case, watch:
Sheila Casey walks you through the hoax. I am convinced that the only victims of the Boston Marathon bombing were the framed Tsarnaev brothers. The older brother was murdered in captivity. The younger brother was also supposed to be killed in the alleged shoot-out with the police, but the operation was botched. The younger brother survived a second episode of police shooting. He was taken into custody, held incommunicato, and assigned an attorney who participated in his conviction. He now awaits execution as his appeals are denied. No one has ever heard his story. We only have alleged confessions, including one allegedly written in his own blood in total darkness as he lay bleeding under the boat where he was found and shot again.
