Again no attempt to answer or reconcile these questions that must be answered to believe this theory.
Jeff had to have both his legs amputated, he is still in the hospital. He has alot of surgeries to go through. I'm guessing he's not worried about the few people gullible enough to believe he is faking it at this point. This is a guy who has friends, family, coworkers and other people that know him and have known him through his life. They know he had legs. His facebook page, his dad's and the page made for his support after the fact all have pictures of him with legs, including some very recent pictures.
Listen to Jeff himself talking to some radio guys that know him personally before the bombing, and have been talking about him since it happened.
