ABC News says it has exposed a crucial weakness in the nation's port security system by shipping depleted uranium from Jakarta, Indonesia, to Los Angeles. Federal officials say the network seems to have committed a crime.

The report by ABC's Brian Ross, scheduled to air tonight on "Primetime Thursday," involves 15 pounds of lead-encased uranium put in a teak trunk along with other furniture in Jakarta, a terrorist hot spot.

[Dennis Murphy] also contended that his department used its contacts to crack the case. But [Jeffrey Schneider] said the government was notified only after an ABC camera crew identified itself to a truck driver hired by the network, who had become suspicious that U.S. Customs agents had missed something at the Los Angeles port.
