The American Civil Liberties Union says The Force, errr, First Amendment is with Sam O’Hara, filing a lawsuit on his behalf after he was handcuffed and detained after following National Guard troops in Washington, D.C. playing the Darth Vader theme from the Star Wars film franchise.

President Donald Trump has deployed National Guard troops and sent ICE agents into multiple U.S. cities during this first year of his second term, claiming it is necessary to combat crime and illegal immigration.

The interference from the feds has invoked strong objections from many of the political leaders and local residents of these areas, with multiple lawsuits filed by elected officials and numerous protests — leading to an additional round of lawsuits as protesters argue the federal government is violating their free speech rights.

O’Hara’s TikTok account, @freedc20009, features dozens of videos of him walking behind or standing near National Guard troops in Washington, D.C., using his phone or a small Bluetooth speaker to play “The Imperial March,” John Williams’ famous musical theme that accompanied the appearance of Darth Vader in Star Wars films beginning with The Empire Strikes Back in 1980. Featured prominently in key plot points throughout the various sequels and prequels in the franchise, “The Imperial March” has been used for years in politically-themed videos and protests to oppose oppressive authoritarian regimes.

The videos posted by O’Hara mostly show the troops ignoring him, and in some cases, even appearing to enjoy the cinematic soundtrack he was providing for their deployment. In the below clips, one Guard member is seen smiling and another is bopping his head along to Williams’ infectious melodies.

Most of the time, O’Hara is ignored by the National Guard troops. In the below post, two Guard members don’t interact with him but do seem to be marching in beat with the music at the beginning of the clip:

In less than two months, O’Hara has built up a sizable following and racked up millions of views for his posts; a post from August has over 4.4 million views alone.

But even Jedi mind tricks couldn’t protect O’Hara from unamused government agents.

According to the complaint filed Thursday in the U.S. District Court for the District of Columbia, on September 11, O’Hara saw several National Guard members in D.C.’s Logan Circle neighborhood and ” stood several feet behind [them], began playing ‘The Imperial March’—the song that announces Darth Vader—aloud on his phone, and started recording.”

“Ohio National Guard member Sgt. Devon Beck was not amused by this satire,” the complaint states, and after “less than two minutes” of O’Hara’s musical protest, Beck “turned around and threatened to call the police officers to ‘handle’ Mr. O’Hara if he did not stop.”
