Green Day's Billie Joe Cited For Indecent Exposure  Billie Joe Armstrong pulled a Jim Morrison on Tuesday (Nov. 21, 96) and exposed himself to 6000 or so fans at the Mecca Auditorium, in Milwaukee, Wisconsin. That was, of course, Armstrong's clever way of letting Green Day fans who understand Green Day-ese know that the Mecca was a mediocre show. Armstrong told ATN during an interview on Halloween that he only drops trou at so-so shows. Unfortunately, this time mooning the crowd, if you'll excuse the expression, backfired. After Green Day finished their hour long set, police officers took Armstrong to the Milwaukee police station, where he was cited for indecent exposure. After he paid the bail of $141.85, he was released. But why don't we let Lt. Thomas Christopher of the Milwaukee PD explain what happened, as only law enforcement can: "Mr. Armstrong dropped his pants to his knees and exposed his buttocks to the crowd. After the concert, Mr. Armstrong was taken into custody, given a city citation for indecent exposure. He posted a bail and was released." Thomas said this was not an actual arrest, and Armstrong is only required to go to court if he intends to contest the charge. Otherwise, he'll commit a "civil forfeiture" and the city will take a "default judgment." Which means if Billie Joe doesn't come back to Milwaukee to fight for his right to drop trou, the city gets to keep the chump change. Officers went out of their way not to disrupt the concert, in order to avoid a potential riot. Instead they waited until the last notes were played and apprehended Armstrong on the way to his limo. "The problem was he exposed himself to a crowd of about 6,000 people," said Lt. Christopher. "Including people as young as ten. That was our main reason for taking the action."
