Senator Joe Lieberman introduced a bill, called Protecting Cyberspace as a National Asset Act which would allow Obama to shut down the Internet in case of a "national security" emergency.
This bill is wrong on so many levels I could write up hundreds of pages on the subject, but one of the main problems is Obama frankly, is in a dream world. He is not connected to reality and is WAY over his head. Therefore he, nor is any government politician qualified to exert control over the Internet. Especially Obama, since he has stated that he wants to control and in some cases shut down news outlets that disagree with him. Or levy special taxes on these outlets to give money for his friends in the mainstream media. And because of this and many other reasons, he can't be trusted with this type of power.
Lately I have been disappointed with Lieberman. He proposes bills like this, but never thinks things through.
