Air Traffic control here, we have another helicopter parent on the scope.
I had to google it...lol. That said, what he said doesn't really make him one either. What he said is reasonable and it is just his opinion so you exaggerating his opinion on the situation because of your opinion is just poop.
My view on it:
If the school hands these out at the beginning of school and then collects them at the end of the day, fine! If the kids are responsible for these, no! It's a security threat that can be abused. So... that enacts my families strict "Go fuck yourself" policy!
