Robert, you're drawing a completely false dichotomy there, namely that "tight" security and human dignity, fairness and accountability are exclusive.

"Training" will not make the system accountable. It will not make secret laws less secret. It will not iterate towards measure that identify a threat and its failure modes and then take steps to address those failure modes.

Secret security is inherently insecure -- and undemocratic. To quote Schneier, "anyone can design a security system that he can't figure out how to break." Secret laws and "security" measures that do not arise from real threats, but rather from an opportunistic drive to roast civil liberties on a pyre of the smouldering 9-11 dead do not make us secure.

When any person at an airport can give any traveller any order and cite secret regulations, and arrest, harrass, black-list and detain any person without cause, oversight or appeal, that does not make us secure.

Arguing that people who don't like it shouldn't travel ignores 100 years of civil rights struggles in America. The right to travel is fundamental -- as the courts have found again and again. Requiring internal passports is something that America nominally spent 50 years arming itself against as an unthinkable abridgement to liberty.

Trade freedom for security -- get neither.
