Supreme Court case on use of deadly force to stop vehicle pursuit

Shortly, the U.S. Supreme Court will hear oral argument on a case that may provide clearer rules on when police can use (and can get qualified immunity) when deadly force is used  to stop a suspect fleeing in a vehicle.  The incident began with a traffic stop for a busted headlight and ended around 10 minutes later with multiple police officers firing a total of 15 rounds into the fleeing vehicle. Killed were the driver, Donald Rickard, and his passenger, Kelly Allen, both of whom were unarmed.  The case is Plumhoff v. Rickard.
