A man arrested after he stripped naked at Portland International Airport was found not guilty of public indecency at a trial Wednesday. John Brennan, a frequent-flying businessman from Portland, set off an explosives wand in April and stripped naked to show Transportation Security Administration screeners he was not carrying a bomb. During the trial, TSA officer Steven Vangordon testified that “he started taking clothes off quickly, I mean he whipped them off pretty fast.” Brennan said he believed he had the right to be naked. “I know the irony of taking off my clothes to protect my privacy,” Brennan said. “They’re getting close to seeing us naked, so I thought I’d up the ante,” he testified. A judge found Brennan not guilty of public indecency on the grounds that he stripped naked as a form of protest, which is protected speech. But things aren’t over for Brennan yet. The TSA is also investigating to see if he possibly interfered with the screening process. If they find him guilty, he could be forced to pay an $11,000 fine and be put on the no-fly list.
