Then read the commentary opposing the use of iris scanners at wired.com/politics/security/commentary/securitymatters/2006/05/70886 (which concludes with the statement: "The real choice is liberty versus control. Tyranny, whether it arises under threat of foreign physical attack or under constant domestic authoritative scrutiny, is still tyranny. Liberty requires security without intrusion, security plus privacy. Widespread police surveillance is the very definition of a police state. And that's why we should champion privacy even when we have nothing to hide.")
