There are a few programs in the U.S. that do that. I got to be part of one back in 2007, News 21, sponsored by the Carnegie Foundation. To your point, just having someone from the outside skeptically examining official claims led to people losing their jobs:

It didn't take much for the leadership change to happen there. I read a few stories about the place getting acquired by a T.V. network with a bad reputation. I interviewed as many people as I could by phone over a few weeks. Then I flew there and spent 3 days wandering the park interviewing as many people as I could. Then I wrote out the story they had told me and my editors worked it over a bit to help it hang together better. When it was published, it didn't seem like I'd actually found anything terribly interesting.
However the simple fact of stitching everyone's testimonies together was enough to show that the company's leaders weren't all telling the story people thought they were, and that led to the ouster.
The News21 program recruited about 100 graduate journalism students, gave us each $7500, and had us report on very narrow topics for 3 months. My team was assigned to "religion and public life" and while this was a private theme park, it was a place where religious themes were displayed very openly. Others in our group went to Mount Rushmore for 4th of July, which is apparently a very religious affair, the Mormon pagaents in upstate NYC, and so on.
