EDIT: CRAP! The title should say "shut down the internet". ISAP.
Should the president be allowed to shut down the internet for whatever reason he/she feels? Would you trust Obama with this power? What about George Bush?
Such a bill is moving through Congress. They are trying to pass it in the night, as they did with the UIGEA. It is S. 773 The Cybersecurity Act of 2009. Section 18 allows the president to shut down the internet for an "emergency". What's an emergency? It doesn't say, we're just supposed to trust them.
The bill also mandates that, even when it's not an emergency, all networks must be run by government-licensed "cybersecurity professionals". That's right, the government wants to take over the internet so that you use it properly.
Contact your representatives and ask them to stop this bill:
