Usual suspects.
Here’s the funny/ironic thing...Kenwood Towne Centre is a rare success story amidst the collapse of the mall biz - it’s expanded numerous times and still draws significant foot traffic (and vehicular traffic). Its offerings, for the most part, are not significantly different from many other malls or open-air facilities but it does enjoy a prime location.
Based on other stories on this incident the ‘teens’ were, as you say, eminently predictable demographically. What this particular account doesn’t say is that the ‘teens’ not only got in an physical altercation, they also went after mall cops and real cops and were trotting out the usual ‘teen’ vocabulary in which b***h is a preferred term of affection.
We are supposed to forgive indiscretions by ‘youths’ and ‘teens’ because they are ‘youths’ and ‘teens’ but the reason such under-18 designations were made in the first place is that under-18s are presumed to be under the watchful eye - and discipline - of their parents. Not only are these feral punks walking the mall on their own but their parents are probably worse than the kids when it comes to lawful behavior.
