People would be crying “Racism” and such.

Possibly even “Hate Crime”

Teacher brutally beats student. 

Not a proportional response. If a teacher can’t handle things better than this, they should not be allowed to be  teaching students.

In the day, a parent or another adult family member would have handled this sort of issue and there would be a lesson learned. And people would have expected things to happen that way. I’d insist on jail time were that my kid.
