Others aren't so obvious. Instead, we will see a dozen or so extras digitized, diddled with and duplicated a few thousand times. We live in a worldwide society where most of us are captured on video tape every day by the stores at which we shop or the companies at which we work. On the other hand, any one of those video tapes could be manipulated by the people with the right tools and knowledge to show us performing any act whatsoever, even at places to which we have never been, or at times during which we were definitely somewhere else. So far even the state of the art can be identified if you know what to look for.
