Please don't descend into strawman arguments and false dilemmas.

It is not a binary choice between the militaristic, public-hostile police we have now, and no police at all.

As it is, the police in schools frequently do inappropriate things, such as bodyslamming 40kg girls or putting children in handcuffs for acting up in class. A school security guard, charged with protecting the students and staff, with no authority to arrest or punish anyone, would do fine.

I think if you throw away the existing system, you can still call what we replace it with "police" but it would be unrecognizable.

We need something closer to social service workers, the vast majority of which do not require arms.
