Isn't that like trying to pulling a rabit out of a hat, when there isn't any rabit there to start with?
When we did do some passenger transport, we had knowledge about the passengers because of past bussiness deals. But I can see how it would be more than posible for a group to pay a 135 operator cash for transport for annonmity.
This is an unreal situation for the despritely poor companies. How could you enforce such a law, with the certainty that "bad" clients are not lying to the operator for starters?
