The problem is a societal one. lets see:
The kids for bullying her for her tan
The school boards implementing the surveillance
The parents who allowed such surveillance in the first place
The person screening what was flagged for not sending the school counselor to talk with the kid
The person calling the cops
The cops for arresting an 8th-grader and DOING A STRIP SEARCH AND KEEPING HER OVERNIGHT WTF instead of handing her over to her parents
This has gone through too many hands to even start blaming the companies. anyone in this chain had the opportunity to do the right thing (ok, maybe the teens didn't, they don't know any better). Noone did.
Surveillance shouldn't be so pervasive, but i have no issue with e.g. surveillance in a prison, maybe in a hospital (not in the patient rooms, but to make sure noone steals the good stuff or to make sure no patients are lost in a service tunnel), at a border, inside of police stations to make sure that prisoner rights are upheld, military bases for obvious reasons and so on.
Your society is the issue, and therefor surveillance is everywhere except where it would be useful.
