"In almost every one of my homicides, this happens: 'I don't know nothin' about nothin', " the prosecutor says. "There is that attitude, 'Don't be a snitch.' And it's condoned by the community." Is it an attempt by drug dealers and gangsters to intimidate witnesses? Is it a legitimate protest against law enforcers' over-reliance on self-serving criminal informers? Or is it bigger than that?Whatever its intent, the Stop Snitching movement has galvanized officials already apoplectic about witness reluctance and witness intimidation. States and localities spend a fraction of what the federal government devotes to witness protection, although this month Pennsylvania restored $1 million for that purpose. The move came as more than a half-dozen witnesses recanted earlier testimony in the trial of men accused in the Philadelphia street shooting death of a third-grade boy. "If the word 'snitch' comes out of someone's mouth, I go insane," says Pellegrini, the Pittsburgh prosecutor. "When young men and women see rappers refuse (to cooperate), they think it's cool. How do we tell them, 'we'll support you,' when they see that?" Especially, she says, when the slogan is blatantly used to intimidate witnesses. Last year, supporters of an accused drug dealer on trial in Pittsburgh federal court wore T-shirts around town bearing witnesses' photos and the inscription "Stop Snitching. " U.S. Attorney Mary Beth Buchanan says one, Garry Smith, had a $100,000 price on his head. "Everybody in law enforcement is beside themselves," says Kennedy of John Jay College. "They can't investigate cases. They can't prosecute cases. The clearance rate for some serious crimes is tanking." Stop Snitching T-shirts have been banned from a number of courthouses. [more]
