Bob Barr made some news today:

Former Georgia congressman Bob Barr, a one-time Republican turned Libertarian, lamented Saturday the loss of privacy because the federal government considers it necessary in the fight against terrorism.

Speaking to the Georgia Libertarian Party's state convention, Barr said Republican and Democratic national leaders were trying to erase the protections of the Bill of Rights, and some citizens seem willing to let that happen because they believe claims that is necessary for national security.

"What this document has come to be in 2008 is different from what was adopted [originally]," Barr said.

He tried to make his point by holding up a copy of the Bill of Rights with almost all the words erased.

Left was a passage from the 4th Amendment— "the right of the people to be secure in their persons, houses, papers and effects ... shall ... be" — followed by five words in the 10th Amendment — "delegated to the United States."

One of the biggest threats now, Barr said, is pending legislation to replace an expired temporary law authorizing warrantless surveillance of electronic communications by suspect terrorists.
