Recently, a police officer in Ohio was acquitted in a criminal case where he jumped on the hood of a car and shot and killed the unarmed driver and his passenger. The judge ruled that under the circumstances of that case, the officer was justified at the time of the shooting to believe that his and fellow officers' lives were in danger. Even though he was acquitted of criminal charges, can the surviving family successfully sue the officer civilly, or is the officer protected by a privilege or immunity from suit? Explain your reasoning.
