PORTLAND, Ore. -

Frequent flying businessman John Brennan set off an explosives wand at Portland International Airport Tuesday and stripped naked to show TSA screeners he was not carrying a bomb.

John Brennan stripped off his clothes at the TSA security station and stood there naked, as waiting passengers and their families looked on, took photos or looked away.

"I am being tired of being hassled by the TSA," he told KGW after leaving jail Tuesday evening.

Brennan said that removing all his clothes was not premeditated. The frequent traveler who had heard of many TSA issues while on prior business travels was just fed up as he set off the detector at PDX.

"And the machine went off, and I asked what it was and he said 'nitrates' which I know from Oklahoma City is one of the explosive ingredients," Brennan told KGW, "and I was not interested in being hassled so I took off my clothes to show them I was not carrying any explosives."

Brennan says he hopes his actions will start a trend.

"I don't think Americans can sit around and put up with this anymore. TSA needs to just do their job and not intimidate people."

A Port of Portland Police report said Brennan was asked several times to put his clothes back on. Two screening lanes were closed for a short time til Brennan was wrapped in a towel and arrested. Alcohol and drugs were not a factor in the incident, police said.

He was taken to the Multnomah County Jail and booked on misdemeanor charges of disorderly conduct and indecent exposure. He was then released on his on own recognizance.

Brennan thinks he committed no crime.

"I know that nude, but not lewd, is protected speech in Oregon," he said.

According to ORS 163.465.

(1) A person commits the crime of public indecency if while in, or in view of, a public place the person performs:

(a) An act of sexual intercourse;

(b) An act of deviate sexual intercourse; or

(c) An act of exposing the genitals of the person with the intent of arousing the sexual desire of the person or another person.

He may have a point. And an annual Portland "naked bike ride" to back up his claim.
