"We have written a blank check on drawn our liberties"

This is Olbermann commenting on the recent law, the Military Commissions Act, which suspended Habeas Corpus. George W Bush and others lied to us a string of claims, lies, that led to the recent signing of this law which suspends Habeas Corpus and other guarantees. It was sold to us as a way to protect freedoms, but are we free if the government can just lock us up with no just cause, not required to show proof of our existence, etc? This has happened in the past, in the United States, when Habeas Corpus was suspended. At times Newspaper journalists and editors have been imprisoned, by the government, for the things they wrote in their newspapers. And more famously during World War II the Japanese descendants living in the U.S. were imprisoned, not because of anything they did, but because they were Japanese. We have entered a new era where the government is now free to do this again.

Here's another video talking about what Habeas Corpus is. It's pointed out the U.S. says, about Habeas Corpus, that it cannot be suspended unless the country finds itself in grave danger such as invasion or rebellion. Now, is the U.S. in actual danger of any invasion?
