Police in Springfield, Illinois set up a sign on Interstate 55 announcing a non-existent drug-enforcement checkpoint. The intent was to entrap any motorist who attempted legally to turn off into a rest area in an effort to avoid the hassle of the roadblock. Those motorists who did so were then subjected to a warrantless search for drugs."The interaction that people feel in those circumstances is not as friendly and uneventful as perhaps the police have suggested," said Ed Yohnka, spokesman for the Illinois branch of the American Civil Liberties Union.Source: State troopers warn of checkpoint, then wait (Rockford Register Star (Illinois), 11/20/2005)
