From San Francisco Chronicle:

A dispute that began after a passenger refused to pull up his sagging pants led to his arrest and removal from a plane at San Francisco International Airport on Wednesday, police said. Deshon Marman, 20, a University of New Mexico football player who was in the city to attend the funeral of a close friend, former Lincoln High School standout David Henderson, was being held at San Mateo County Jail on suspicion of trespassing, battery and resisting arrest.

Marman grew up a block from Henderson in the Bayview neighborhood, and the two were teammates at Lincoln High School and City College of San Francisco before they transferred to separate four-year universities.

Henderson was shot May 26 on Kirkwood Avenue and died 11 days later.

On Wednesday, San Francisco police got a call about 9 a.m. that someone was exposing himself outside a US Airways gate, Sgt. Michael Rodriguez said.

An airline employee spotted Marman before he boarded Flight 488, bound for Albuquerque, and complained that Marman's pants "were below his buttocks but above the knees, and that much of his boxer shorts were exposed," Rodriguez said.

The employee asked Marman to pull up his pants before he boarded the plane, but he refused, Rodriguez said. Marman allegedly repeated his refusal after taking his seat on the plane.

"At that point he was asked to leave the plane," Rodriguez said. "It took 15 to 20 minutes of talking to get him to leave the plane, and he was arrested for trespassing." Marman allegedly resisted officers as he was being led away.

Marman's mother, Donna Doyle, said he was still in an emotionally raw state after attending Henderson's funeral Tuesday, where he spoke of his intention to honor his friend's memory by making it to the NFL.

Doyle said she had encouraged her son to leave soon after the funeral.
"I didn't want him to stay here in the city because of what happened to David," Doyle said. "A lot of it is jealousy. These kids are trying to make it, they're going off to college and other people get jealous."

She added that her son was targeted at the airport "because of the way he looks - young black man with dreads and baggy pants. But he's a good kid trying to make it, and he's going through a lot. And then this happens."

Valerie Wunder, a spokeswoman for US Airways, said the airline's dress code forbids "indecent exposure or inappropriate" attire.
Marman was being held on $11,000 bail.

Jake Tommerup, 57, of Phoenix, who was aboard flight 488, said he had been annoyed by the hour-and-a-half delay. But he also said he was stunned by US Airways' reaction to what, in Tommerup's mind, amounted to little more than a questionable fashion choice.

"When I get on a plane and see a 13-year-old girl with her whale tail" - exposed G-string underwear - "and fat old white guys with plumber's crack sitting down, and middle-aged ladies in halter tops and tons of cleavage - if you're not going to kick those people off the plane or ask them to cover up, then let's admit the hypocrisy."
