A call comes over dispatch that a security guard at a shopping mall in a predominantly white neighborhood has seen four Hispanic males. The security guard reports that they are gang members because they are all wearing matching leather jackets and red ball caps. He reports that they have just opened and closed their car trunk and are now entering the mall. The security guard notifies the merchants, some of whom immediately begin closing their stores. You are the officer in the vicinity of the mall who responds to the call just as the juveniles are leaving the mall and are heading toward their car. In the meantime, several merchants continue to be anxious about the "gang members," leaving their stores closed.
What should happen?
