Whether or not to get involved in a high speed chase with a person wanted for a crime is always a difficult decision for police. On one hand there is the motivation to apprehend the person who is fleeing and on the other is the consideration of the danger that such a chase poses, not only for the fugitive and the police themselves but also for the public at large. When innocent people on the highway get hurt, the police may be guilty of negligence.
A Detroit couple sued the police department after they received permanent injuries when they were hit from behind by the car that the police were chasing, causing them to crash into a telephone pole.
Generally police will be held responsible for damages or injuries resulting from the risk posed by a high speed chase.
