A Lenawee County circuit judge has not yet set a date for a hearing on whether to bar Daniel Kennedy, Wayne State University criminal justice professor, from testifying as an expert defense witness on behalf of the defense in a case against a state trooper who shot into the car of a suspect who was fleeing from police. The state Attorney General's Office, on behalf of the trooper, has proposed putting Kennedy on the stand to give his opinion on the mental states of the shooting victim, who died, and the trooper, who says he shot in self defense. The victim's family brought suit against the officer.
