it's been suggested by some that kennedy's vice president lyndon johnson ordered the hit on his boss. in fact, johnson who set up the warrant commission in part to put an end to the chatter that he was responsible for the assassination. but the chatter continues. especially since sheenan found so much evidence was destroyed. >> president kennedy dies on friday. on saturday night, his original autopsy report and all of the notes from the autopsy room are pushed into one of the doctor's fireplaces where it turned to ash. the next day, you have fbi agents in dallas shredding a note that oswald had left for them a few weeks earlier. a handwritten note and we never know what is in that note and flushed down the toilet. over time more and more evidence would disappear from government files. >> which only feeds the conspiracy? >> absolutely. so many of the conspiracy theories are created by the government that was supposedly trying to combat it.
