If you watch a lot of police procedurals, you’ll recognize this setup: beat cops get a visit from Internal Affairs and drama ensues.  As it turns out, government agencies also have their own internal watchdogs: investigators that make sure  federal policymakers are following the law. In this episode, we learn about the role and origin of inspectors general.  How do they launch investigations? To whom do they report? And is the position influenced by politics?  Our guest is Elizabeth Hempowicz, Director of Public Policy for the Project on Government Oversight.
