Teachers can weaponize CPS reports and absolutely cause legal problems. I know someone who dealt with that. Their kid's doctor put the kid on an ADHD medicine, he had a bad reaction to it, and then the doctor told the mother to immediately discontinue it.

The teacher was annoyed the kid was kind of disruptive and so filed a report that the mom had committed "medical neglect" for not giving her son the meds.

She had to take off work and deal with random CPS visits until they were satisfied.

This is a kid with good grades who can read multiple grade levels higher and who is most likely bored in class. I think he was in the first grade at the time

I don't know what the consequences of that are or could have been but it raised my eyebrows
