The feds offer grants to states to help them fight DUIs, including financing overtime pay for troopers writing citations to impaired drivers. Gadzooks! Two Mississippi highway safety officials learn of an internal investigation probing whether state troopers were writing ghost tickets to tap into that sweet overtime pay. The two officials tell the feds, the feds stop funding Mississippi, and the two are fired. First Amendment retaliation? Fifth Circuit: Nope. Their statements were made within their job duties and thus are not protected by the First Amendment.
