Janet Lee's lawyers told the Philadelphia Inquirer the main issue is field tests that supposedly found the white powder in her luggage was drugs.

Jeremy Ibrahim and David Oh say that, given the general reliability of field tests, either the results were deliberately falsified or the people doing them blundered badly.

Laboratory tests confirmed the substance was, as Lee had said, flour.

Lee was arrested two years ago at Philadelphia International Airport as she tried to board a flight home for Christmas from her freshman year at Bryn Mawr College, an academically rigorous women's school. She tried to explain that the flour-filled condoms were a joke and a stress reliever but was told they had tested positive for amphetamines, opium and cocaine.

Oh, who became involved with the case early, said he was suspicious because drug couriers do not mix drugs like that.
