CBS News reporters uncover security lapses in Los Alamos National Laboratory, a U.S. weapons laboratory. In some cases the labs failed to check visas and passports of foreign workers, even after the 9-11 attacks. Two former employees were fired after trying to expose acts of fraud and mismanagement within the labs. The reports also showed that a large number of equipment and supplies were "missing" and/or "stolen," many of which cost thousands or millions of tax dollars. Reporters also exposed a misappropriation of even more tax dollars as some employees were discovered to have spent millions on "questionable purchases" for VCRs, trips to the spa, and diamond rings. One employee who was trusted with a million dollar a month credit line charged a $30,000 custom Mustang to the government credit card, and received no penalty for her actions.
