Egypt can turn off the Internet but it can’t stop satellite TV, Twitter or ham radio operators.

Al Jazeera is reporting that state security is trying to enter the building where their Cairo bureau is located. NPR’s Andy Carvin tweeted, “Al Jazeera streaming live video from their office window; police are banging on the door trying to get them to stop.” Followed by a quote from Al Jazeera, “We’ve been streaming live for 5 hrs and the police are clearly not happy about it.” The Raw Story reports that the station may be shut down, but the live feed from Al Jazeera English is still streaming, with reporters breaking the news from Egyptian state media that Mubarak has ordered police reinforcement for the curfew set from 6 p.m. local time, now in place, through to 7 a.m. on Saturday. “It’s not having any effect.”

Here’s raw video that was posted on Youtube five hours ago. It gives you a sense of just how massive the protests in Cairo are. It was shot by Mohamed Ibrahim Elmasry, “a professor emeritus of computer science at a Canadian university who is in Cairo.”

Riot police are firing off tear gas canisters but it’s not stopping the protesters. The will of the people is awe inspiring.
