You are walking thru the parking lot of a retail store. Your attention is drawn to a male pulling a young girl, 8 or 10 years of age, by the forearm toward a parked car. She is screaming and throwing a fit. He is telling her to shut up. He picks her up and puts her in the front passenger seat and closes door. See's you watching and yell's " what are you looking at" as he opens drivers door you hear "I don't know you, where is mommy?" ... What do you do now? Call the police with a description and plate #. Ask if there is a problem. Ignore the situation.
