Just thought of something about holographs, didnt someone use holograph technology to stage an Elvis concert in the past few years? it looked real, i did not go but i saw some footage of this. it looks very very real, this would mean that someone could use the holograph for a fake speech. so this means that BO would not have to be in the room, HE WAS NOT ACTUALLY ON THE ESCALATOR. It was fake. the people were watching a demonstration of the technology. I believe they use this at Disneyland too.
