In Times Square, hundreds of thousands of people are milling around. Everyone was moving past the newly installed high-def screens during a "Good Morning America" broadcast.
Meanwhile, in Nevada, the roads were empty (rush hour is when 5 cars come in a hour. That's actually the legal definition there).
Back in Times Square, the screens all flicked off and emitted screeching noises at 127 decibels for 1.27 seconds. The noise then stopped and the screen switched to displaying the empty, streetlight-lit Nevada road for 12 seconds..
The glitches then escalate into randomness, ending with a message "Submit to us". Then the screens fell off (yes, all of them), hitting some people.
What would be a realistic response from the mass of humanity there? Additionally, what would the reactions be for the Good Morning America anchors?
