From Bruce Schneiers most recent Crypto-Gram

The U.S. system of government has a basic unwritten rule: the

government should be granted only limited power, and for limited

purposes, because of the certainty that government power will be

abused. We 've already seen the US-PATRIOT Act powers granted to the

government to combat terrorism directed against common

crimes. Allowing the government to create the infrastructure to

collect biometric information on everyone it can is not a power we

should grant the government lightly. It 's something we would have

expected in former East Germany, Iraq, or the Soviet Union. In all of

these countries greater government control meant less security for

citizens, and the results in the U.S. will be no different. It 's bad

civic hygiene to build an infrastructure that can be used to facilitate

a police state.
