Sarah Rogers is a very politically active, private citizen. She decided she wished to protest the President's policy on the environment. Therefore, she went to Washington, DC, and across the street from the White House, she peacefully protested by marching with a sign that read, "YOU DO NOTHING TO PROTECT OUR PLANET."

The capital police arrested her because they stated, "The sign was untrue and will confuse the innocent public."

Does the First Amendment of the constitution protect Ms. Roger's right to carry this sign, or did the police have a right to arrest her? Be sure address the classification of speech her sign falls within and how the classification impacts your analysis.
