I'm glad to see you have begun to explore the wealth of material posted at that blog, mon. I get RSS updates from there and several hundred other sites and only post a very few of the highlights here.
I suspect that the IG posts are just another part of the political machine that provides salaries for doing very little AT OUR EXPENSE. IG investigators should be feared by bureaucrats, but instead those charged with oversight of our institutions fear so much for their own fat jobs that looking the other way (or not looking at all) has become the norm.
Remember Gerald Walpin, the IG that Obama fired? He lost his appeal, you know, and that signaled the end of integrity for the Inspectors General.
