@Tekla58231@MalconSxRD Yes, they would be safe from shock. It's the same principle as stated in the video. As long as there is no connection to a ground source, the current won't travel through the body.
@ZNASCOOL@MinMedio Actually, the video is taken directly from a cell phone that recorded what was being viewed on the video footage of a computer screen. None of the cameras were focused directly on the customers or thieves. The cameras were focused on the general areas of the store.
