Biden Ear Piece

I know there was talk about checking for an ear piece and at first I said yeah right who in their right mind would allow that to happen (putting an ear device in Joe's ear). But as I watched the debate, each time Biden would lose control (which he never had LOL), he would turn to the camera and start taking most of the time about going to vote. The man is not cognizant enough to do that on his own. Someone was telling what to do. Next debate someone needs to have a device in the audience to create a problem with someone having an ear piece, like a high pitch noise (not sure if that is possible) but can you imagine if it did happen....Joe would go crazy. (oh well to bad for those in the audience with a hearing aid...sorry)
