They certainly shouldn't be treating one group clearly different than another clearly on the basis of race. An attorney in your area might be willing to challenge this policy as a violation of your fundamental rights to equal protection and free assembly. Racial profiling, which is what they must be doing, is unconstitutional in a public or semipublic forum. Malls are in that category.. . But now I have a question for you. Why on earth would you want to travel in a pack of ten or more people? You do not want to be judged based upon the behavior of the least-well-behaved member of your group, and you cannot possibly control all of the members of a group that large. Way back when, when I worked in retail, we would never have allowed ANY group that large to come into our store and shop as a group. There were many reasons why (noise, litter, shoplifting--and, yes, the potential for shoplifting IS greater when a huge group of teens come into a mall store--and harassment of other customers, for example). . . Since you seem to care about your reputation, as well you should, please recognize that your reputation will suffer if you are perceived as part of a group where the least of your members behaves badly.
