under what authority can the police prevent students from leaving campus? truancy laws? I don't think those would apply to students who are 16 or older, certainly not to those who are 18. And I seriously doubt truancy laws can be used in this manner - students may have their parent's permision to leave for all the police know. A student leaving school and going home with his parent's permission wouldn't be guilty of truancy.

Did the kid bring a note? The parent needs to send a note or talk to an administrator by phone. The school usually gives the kid a pass of some kind to leave. I doubt this happened with all of these kids. Truant.

Tensions arose at the school just before noon, when several hundred students tried to leave campus in protest of proposed immigration policies.

Hello, permits and the like? Plus the fact that some of these cherubs were hurling concrete at John Law.

I just know that in our area - that if a school is in lockdown mode, no students may leave, note from mommy or not. I did not see where this school was officially in lockdown mode other than the locked gate.

Here in Houston there is a curfew ordinance. That's what they're arresting them on.
