Based on what's reported in the news story, we just don't know. It references a state law that school officials were following, but the author of the article did not quote any of that law, or provide the section that was alleged to be violated. It talks about police procedure but also does not reference a specific procedure. It may be the agency has a "zero tolerance" for those types of violations based on their history in dealing with them. We just don't know.

It would have been nice if the author went into more details about the procedures and laws. Perhaps we might see a followup article going into a little more detail about the procedures and laws involved here, and then decide whether anyone needs to be held accountable for their actions. There's just not enough detail in the story for me.
