I'm not sure I follow your analogy
I'll clarify. Suppose a city has ordinances requiring certain building codes be followed for new construction.
In some cities the city employs all its own inspectors. If just one of those inspectors can be bribed, does that really mean the organization (city) is not serious about the codes being followed? That seems a stretch.
In other cities, in addition to city employees, there are 3rd party consulting companies that can perform inspections, prepare reports, and submit them to the city. Provided the building developer provides the city a report done by one of these companies, the city will authorize an occupancy permit or whatever. So now if one employee of one of the consulting companies is corrupt does that really mean the city is somehow corrupt or not serious about buildings being to code? That seems a huge stretch.
Similarly, in many cases things like "environmental impact assessments" are not done by the country itself, instead they are done by universitys, researchers, and dedicated consulting companies. If you can find a student research or consultancy employee willing to fudge some data to get a 'pass'... that hardly means the whole country isn't serious about the environment.
If some corrupt organization granted the filming permits when they weren't supposed to, the government can always revoke them anyways.
Of course.
