Just like any group, organization, family, company, establishment: A fish rots from the head down.
The system has to be setup in such a way, that the heads of an organization are least likely to start "rotting":
- checks and balances
- personal liability
- transparency
Looks like a pretty easy to spot "hidden" advertisement to me. Don't believe anything you read on the internet unless you can and will verify it. Same applies to newspapers, but I guess the internet being a more dynamic place it is a lot tougher to sort out truth from lies so you best be safe not believing anything out there unless, as I said, you verify it.
