IS THE U.S. MOVING TOWARDS A NATIONAL ID?

From the Cato Handbook on Policy, 6th Edition: http://www.cato.org/pubs/handbook/hb109/index.html Every policy proposal should be carefully examined for effectiveness and consistency with our values and freedoms. A national or uniform ID system offers less protection at greater cost to freedom than it appears to. Verifying identity is just one, fallible, way of attempting to secure transportation systems and infrastructure. A national or uniform ID system would be a small but significant step toward future impingements on freedom, including mandates that all Americans carry identity cards at all times, the creation of an internal passport system, and government tracking of individuals’ travels and financial transactions.

Congress should resist the establishment of a national identification card and encourage the development and acceptance of private identification systems. Read the rest of the chapter here: http://www.cato.org/pubs/handbook/hb109/hb_109-27.pdf
