It is a known fact that a large number of thefts are in mall car parks. It is also a known fact that theaters are a high risk due to thiefs know how long you will be away from your car.....so a theater in a mall is the highest risk of all. You were lucky that the security guy saw your car and if I was you I would call the mall managers and let them know what that security guy did. Be advised if you have a nice car or a classic do not take it to a mall. If you can't see it...you can't protect it.
