1)A tweet came across less than 10 minutes ago saying TV coverage of Tahrir Square was vastly reduced. 2)Journalists are being rounded up. The Tiananmen Square massacre began at night, and when the media was disabled. 3)Mubarak was interviewed at his palace less than 2 hours ago. Now making his location known - at the normal, symbolic location for a head of government. Protestors - IF the lights go out in Tahrir Square, the crackdown will begin in a few minutes. Journalists - keep those cameras rolling! Especially the ones that are night-vision enabled.
