Im actually surprised that security didnt go batcrap crazy! I used to work security there and ALL GGP properties are considered "gun free zones". When I worked I heard about an OCer getting booted from the western store/mall that used to be at the Sears exit. Go figure, a lot of these mall shootings happen on GGP property.
Im guessing nobody noticed... or atleast nobody stupid noticed. Maybe not the best sign of the current crop there though. Supposed to be observant.
