It would be interesting to know what the chaperone status was. How many? Who? What experience they had managing a large group of h.s. students. I’d be surprised if they could get as many as our local guidelines require for field trips. (IIRC 1 chaperone for 5 students, in h.s., more in e.s.). I’m not sure, either, how anyone could work/teach in a school where there were so many misbehaving/disrespectful students.
These students "feral thugs" weren't misbehaving or being disrespectful. They were scoring high grades doing just what they have been taught in public schools nowadays...exercising their self-esteem and building up their self-confidence in order to create more mayhem and cause more damage in their future careers as society's criminals.
Of course, none of them know readin', writin', 'rithmetic or respect. That's only for those racist, white privileged kids.
