Jamming the camera or overloading it is itself a tell. Knowing the exact location and geometry of a camera lens makes it feasible to spoof the scene by placing a fixed image below the camera. Unless the camera has a zoom, which is unlikely, a simple affine transformation of a real "lap" is enough. Make it of a lap covered with a blanket and then even the lack of movement will not be a tell. --Tim May "They played all kinds of games, kept the House in session all night, and it was a very complicated bill. Maybe a handful of staffers actually read it, but the bill definitely was not available to members before the vote." --Rep.
