I've heard of kids who have had them follow them home from school or even stop them in the middle of the school hallway.

I never had to deal with them, but they apparently can just walk into school in the middle of the day.

People really don't understand just how dystopian the US is and how much of it we take for granted because we grew up in a place where it's normal for elementary students to pledge their undying loyalty to a flag every morning before class starts.
