Early this month, Stacy Abney finished paying another in his long, loopy string of debts to society. This one cost him 6 months and 19 days, during which time he celebrated his 82nd birthday in the unlikeliest of places: the Department of Corrections' Youth Center No. 1 in Lorton. Gramps visits the Planet of the Punks. That gross mismatch of person and.place seems the ultimate ad- mission on the part of the criminal justice system that it doesn't quite know what to do with-much less what to make of-Stacy Abney. By his own count, in the past 18 years Abney has been arrest- ed 57 times. Records show he subsequently was hauled into court on at least 13 occasions, and convicted on about half those charges. He is uncertain how long he has cumulatively been behind bars. "But it's a gang of time," Stacy mutters. "It's around six or seven years. The dates change. The crime and the crime scene never do. One misdemeanor appears over and over and over on Abney's rap sheet: "Unlawful entry, U.S. Capitol." Unlawful entry is legal pato¡s for trespassing, which in the case of Stacy Abney translates to refusing to leave the premises he has occupied, except for jail time, for nearly two decades. Only the president of the United States can boast of having a more prestigious home address than Stacy Abney. The downside for the president is that every four years he has to beg 250 million landl8rds to renew his lease. Stacy doesn't ask anybody for any- thing, ettcept maybe a little change. Stacy Abney's life of crime can be best expressed as an apho- rism: The man's home is his hassle. For 18 years he has been liWlg in the c rriageway underneath the main steps on the east side df the Capitol building. He doesn't smoke, doesn't drink and has delib- erately distilled his existence to a few hunks of cardboard, a blanket and a couple of small boxes neatly filled with spare clothes. He is as consistent in his own way as the law of gravity; a human subway train that makes only two stops: jail and Capitol Hill. "Stacy has a particular, I guess, mental bent, and nobody's ever gonna change his mind," explains J.G. Lewis, one marcher in the parade of public defenders who have drawn Abney's cases. "You could probably cut his arms and legs off and he would still be back there." Stacy Abne isn't just another homeless person; he is a home- less protester. He wants redress from his government. Think of him as a round-shouldered, 6-foot-2-inch, 175-pound eternal flame of discontent. Burning, burning, burning. Through rain, sleet, snow and pigeon droppings. Through five presidencies. Through rising hemlines and the fall of communism. Through the entire run of "Cheers." Through three James Bonds and three Redskins Super Bowl victories. Burning, burning, burning. His consecutive streak puts Cal Ripken's to shame. On June 15, 1975, Abney left home in East Texas and boarded a Trailways bus bound for Washington. OnJune 17 he began a one-man, round- the-clock, round-the-calendar vigil, starting in Lafayette Square and quickly relocating to the Capitol steps. It took him 16 days to get his first arrest under his belt. The target of his protest was, and re- mains. the Department of Veterans Affairs, which Abney claims owes him more generous benefits than it has coughed up - assosted ailments'he says he suffered h World War II. In 1946, the VA granted h£n a mod- est serviceconnected physical disabili- ty auowance. For years afterward, Ab- ney complained to VA representatives, politicians and servicemen's organiza- tions in Texas~before heading north to stir things up Tbe fed-tl government rates him 2O percent good for $162 a month. AbnŠy, h•wever, doesn't see a dime. VA rules require that checks be deposited promptly to continue one's eligibility, Abney techni- cally forfeited a~ tieni-¤ts when he stopped cashing his checks in a huff some seven years ago.' Abney is con- Wred his body's wracked with 100 percent-level pain, all of it war-related. He's all "buggered up," he says. Aches from head to toe. Chest pa—ls. Ball
