Carter filed a lawsuit claiming that his First Amendment rights had been violated, which is now before the U.S. Court of Appeals for the 4th Circuit. Both Mr. Carter and Mr. Van Buren's "speech" raise substantial constitutional questions and create the appearance of impermissible retaliation for their criticism – Carter's so tacit that you can't even call it "criticism," and Van Buren's more open – of the head of the sheriff's department and the State Department, respectively.

The Supreme Court has made clear (Pickering v. Bd. or Educ., 1960 and its progeny) that public employees are protected by the First Amendment when they engage in speech about matters of public concern. These rights can be overcome only if the employee's interest in the speech is outweighed by the government's interest in the orderly operation of the public workplace and the efficient delivery of public services by public employees.

The Supreme Court has also held that public employees retain their First Amendment rights when speaking about issues directly related to their employment, as long as they are speaking as private citizens (Garcetti v. Ceballos, 2006). It is clear in both these cases that both Mr. Carter and Mr. Van Buren were "speaking" in their own voice and not on behalf of the local Police Department or the federal State Department.
