You, being law enforcement, the direction, as I understand, would be to simply ask the driver where the firearm is located in the vehicle correct? Then determine the situation and can even ask the driver to hold onto the steering wheel while you locate the firearm if you were uncomfortable with the situation. It would seem vocally establishing the location of the weapon would be an officer's first motive. The man was shot with his gf in passenger seat and his little girl in the back seat. As far as threat level one would think the threat was low. It would be insightful to know your opinion.
