It's the same thing, phrased two different ways. There's not some magical action any school administrator can take to make poorly raised kids behave. Especially in an understaffed school. You can make them leave the school, which removes the problem temporarily, but then what? Truancy is already a problem, expelling more kids is not going to fix the problem. The US already has one of the largest criminal underclasses on the planet. Fixing a classroom by ignoring tough situations just kicks the can down the road. Your kid will have a nice classroom experience, and when they graduate, they'll be robbed by the kid they didn't have to sit by.

IMO this entire problem was caused by segregating our schools to begin with. The problem of misbehaving kids isn't going to be fixed by giving them free vacation on the streets. They need to see with their own eyes that their behavior isn't acceptable, and that means putting them in environments where they are outsiders. Kids are a product of their social environment, full stop.
