TSA to swab airline passengers' hands in search for explosives - CNN.com

"The American Civil Liberties Union has 'always supported explosive detection as a good form of security that doesn't really invade privacy,' said Jay Stanley, an attorney and privacy expert with the organization.

Stanley said the ACLU is chiefly concerned that the TSA does not discriminate when selecting people for enhanced screening -- something the agency said it does not do -- and that it treat people with dignity.

'We would not want to see it implemented in a discriminatory fashion, for example, in a disproportionate way against Muslims and Arabs or, for example, people with red hair or anything else. Security experts from across the spectrum will tell you that that's not just unfair and unjust and not the American way, it's also a terrible way to do security,' Stanley said."
