The clowns in charge forgot that this is the nation‘s capitol.

In Washington, D.C., it is illegal to talk about the monuments or the history of the city if a person pays you to take them around town. That is, unless you pay the government $200 and pass a 100 question multiple-choice exam.

The District requires that all tour guides get a tour operator’s license, which can be obtained by paying an application fee, a license fee and an exam fee, all of which total $200, and taking the exam. The penalty for failing to do so is up to 90 days in jail and/or a fine of up to $300.

That is a risk that Tonia Edwards and Bill Main take daily. The two operate Segs in the City, a tour company that conducts people around the city on Segways. Neither they nor their employees have the required license. And, they have no intention of getting one: On Thursday, Edwards and Main, with the help of Institute for Justice, a libertarian public interest law firm, filed suit against the city.

For Main, Edwards, and IJ, it is an issue of free speech: “The Constitution does not allow the government to be in the business of deciding who is — and who is not — allowed to speak about various topics.” Standing at the U.S. Navy Memorial, across the street from the National Archives where the U.S. Constitution is housed, Robert McNamara, staff attorney at IJ, declared: “That is un-American, that is unconstitutional and we will put a stop to it.”
