CNN's assertion that this was a glitch may be true, however, as a long-time, highly experienced, industrial electronics repair technician, now software engineer for the largest automation controls company in the U.S., I can say that IF this really was a "glitch", it could have occured at any time. That this occured when an image of our vice president was on the on-air screen raises my intrest a great deal. If a person could have directed the equipment to put the X up on the on-air screen, then let CNN say so and let's find out if that happened. And, if it did happen that way, let's find out why. If it was an equipment glitch, then let's find out why. Also, IF it really was a glitch, it should occur again sometime. This piece of equipment can be taken out of service and be brought into the "shop" for inspection. The hardware and software can be reviewed and scrutinized for possible causes and corrective action can be taken so this doesn't happen again. CNN and other broadcasters should want that assurance, shouldn't they? I believe that CNN should be made to show that this piece of equipment actually had a problem to prove their assertion of there being a "glitch". If they do not, or say that they will not because they feel that they don't have to prove anything to anybody, then that makes their assertion of a glitch even more suspect. I think that it's finally time for CNN to put up or shut up. I think that we have the right to demand this, what with their supposed to acting in the public intrest by broadcasting on the public airwaves as their license states.
