I care that there are students here screwing around, out of school during school hours, in broad daylight and the principal and truant officers do nothing.

You are focusing in on the disorderly event itself. In that regard, I agree with you. The police should be enforcing the law. The kids are by law to be in the school and not marching.
My point addresses a larger issue: Government schools can not respect First Amendment Rights and at the same time maintain a safe, education focused, and orderly environment for the children.
It is for this reason that we must work to begin the privatization of universal K-12 education.
That's a problem of the school's own making. The reason they can't is because they insist on "diversity". The Mexican or any other national flag has no place in our schools but for educational purposes only.
