Yes I know a few guys in customs who are paid to look other way and they use CHA to benefit from such thing (so they aren't directly involved by indirectly involved through CHA) when caught they blame it on people working under them
In most countries customs is a law enforcement agency (exercising the government’s policing power) not a regulatory agency (exercising the government’s policy-making power).
That seems illegal. Who's looking the other way on that?
