IIRC, if a law enforcement officer catches someone carrying that much cash on their person, the officer can simply seize the cash without filing any charges. Not likely to happen with the Gore family, though.
Given what Albore III was arrested for, they should have been allowed to assume that anyone carrying $20K cash on his behalf might be involved in drug trafficking...... they could have tossed her in the slammer with little ‘bro while they sorted it all out!!
