So the driver didn't secure the seal on his wagon before he left the factory. On site security should have checked this but didn't - if they had the situation wouldn't have arisen at all and there would be no story.
If the airport security had checked the wagon, as customs do for illegal immigrants, then the reporter would have been detected.
I am sure that both the driver and the reporter would have been arrested and prosecuted and probably sacked if they had been discovered.
The driver surely realised the consequences if he had been discovered and was prepared to take the risk to highlight the lack of security.
As others have said, don't shoot the messenger
