Police Chases The Supreme Court ruled today that police can't be sued for most high speed chases that leave someone dead or injured. The Justices ruled that police can be sued only if their actions are so extreme that they would "shock the conscience." The case involved a California teenager who was a passenger on a motorcycle that a deputy sheriff was chasing. When the motorcycle stopped suddenly, the deputy's car hit the teenager and killed him.
