Minutes before the President of the United States would tell the Congress how much he appreciates “responsible criticism and counsel,” the mother of a soldier killed in Iraq was dragged from a gallery overlooking the House chamber where Bush would speak, handcuffed and arrested for the “crime” of wearing a T-shirt that read: “2245 Dead. How many more?”

Cindy Sheehan, who had been invited to attend George Bush’s State of the Union address by Representative Lynn Woolsey, the California Democrat who co-chairs the Congressional Progressive Caucus, did not put the “dangerous” shirt on for the event. The woman whose protest last summer outside the President’s ranchette in Crawford, Texas, drew international attention to the antiwar movement, had been wearing it at events earlier in the day.

Indeed, as Sheehan, who had passed through Capitol security monitors without incident, noted, “I knew that I couldn’t disrupt the address because Lynn had given me the ticket and I didn’t want to be disruptive out of respect for her.”

No one has suggested that Sheehan was in any way disruptive.

So why was she arrested?

Because, as Sheehan recounts, she was identified as a dissident.

Before the arrest, media reports buzzed about official concern regarding Sheehan’s presence. And, as she was being dragged from a room where the President would shortly extol the virtues of freedom and liberty, police explicitly told Sheehan that she was being removed “because you were protesting.”

Capitol Police and other security officials, whose rough treatment of Sheehan was witnessed by dozens of people who attended the State of the Union event, said she was arrested for “unlawful conduct.” Conveniently, she was held until after the President finished speaking.

Is there really a law against wearing a political T-shirt to the State of the Union address?

No.

The Capitol Police, who on Wednesday dropped the charges against Sheehan, have acknowledged in an official statement that: “While officers acted in a manner consistent with the rules of decorum enforced by the department in the House Gallery for years, neither Mrs. Sheehan’s manner of dress or initial conduct warranted law enforcement intervention.”

What they have not acknowledged, and what is truly troubling, is the evidence that Sheehan was singled out for rough justice.

Beverly Young, the wife of Representative C.W. Bill Young, a Florida Republican who chairs the House Defense Appropriations subcommittee, showed for the State of the Union address up sporting a T-shirt that read, “Support the Troops–Defending Our Freedom.” When Capitol Police asked her to leave the gallery because she was wearing clothing that featured a political message, Mrs. Young says, she argued loudly with officers and called one of them “an idiot.”

But Mrs. Young was not handcuffed. She was not dragged from the Capitol. She was not arrested. She was not jailed.

Sheehan, who caused no ruckus, was arrested not because she engaged in “unlawful conduct.” Rather, by every evidence, she was arrested because of what her T-shirt said–and, by extension, because of what she believes.

That makes this a most serious matter. Representative Pete Stark, the California Democrat who is one of the senior members of the House, is right when he says that Sheehan’s arrest by officers he refers to as “the President’s Gestapo,” tells us a lot more about the George Bush and the sorry state of our basic liberties in the midst of the President’s open-ended “war on terror” than anything that was said in the State of the Union address. “It shows he still has a thin skin,” Stark says of the President who claims to welcome dissent.

It also shows that the father of the Constitution, James Madison, was right when he warned that, in times of war, the greatest danger to America would not be foreign foes but Presidents and their minions, who would abuse the powers of the executive branch with the purpose of “subduing the force of the people.”

This one incident involving one T-shirt is a minor matter. But seen in the context of the mounting evidence of constraints on legitimate protest, warrantless wiretaps and the abuses of the Patriot Act, it reminds us of the the truth of Madison’s warning that: “No nation could preserve its freedom in the midst of continual warfare.”
