A man suing the District of Columbia claims police officers violated his free speech rights when they detained him for following an Ohio National Guard patrol while playing Darth Vader’s theme song from “Star Wars” on his phone. American Civil Liberties Union attorneys filed Sam O’Hara’s federal lawsuit Thursday. The lawsuit says “The Imperial March” is the soundtrack of O’Hara’s peaceful protests against President Donald Trump’s deployment of Guard members in Washington, D.C. O’Hara says he didn’t interfere with the Ohio troops during their Sept. 11 encounter. One of the troops summoned officers, who kept O’Hara handcuffed for several minutes before releasing him without charges.
