Earlier quoted context omitted.
The text of the Compact: > Signatories commit to using lawful force if necessary to prevent these violations and to swift, serious, and consistent sanctions for those who commit them. Many students enter college as minors, so this is asking colleges to commit to using force against minors while only talking about hypothetical events.
What's wrong with that? They're still covered by the law.
1. Many people have an aversion to harming children. This aversion is not universally shared, but it is a very common stance nonetheless. Children, especially, tend to have an aversion to being harmed.
2. Universities need to recruit children to leave their families and be governed by them (e.g. housing, food, etc.).
3. Parents of children are required to get approval for those children to go to the universities, so that the universities can function.
4. It is harder to recruit children to a university that has agreed that in vague circumstances it is ready to harm them. Note here that everyone already knows that there are sanctions for breaking the law, and that the university is advertising that it is willing to go above and beyond normal law enforcement procedures in hurting children.
Does that clarify?
