Why don't schools have a response staff for unruly children that doesn't involve police or security officers. They should have people trained to deescalate children with behavioral issues throwing tantrums or kids with special needs acting out their frustrations. Imagine the work that could be done with that approach instead of criminalizing children and turning everything into an incident.
This is an exercise of freedom of religion within a public institution. It is never acceptable to compel a student in a public school to do something contrary to his beliefs. A student has no obligation to give a prayer that contains a clear violation of his beliefs, to perform an act that his religious beliefs hold as idolatrous, to deny one's religious beliefs or tenets, or to experience a mockery of his religious views.
I had to tread lightly on a Satanist, of all things. You can just imagine how objectionable Satanism is to me, as I would never imagine worshiping an entity who would destroy Humanity in its service. But someone did, probably to shock me, and all I could say was to recite a portion of the First Amendment regarding religious freedom. I could notice that his ritual cadged pieces of the Roman Catholic Mass and a Masonic ceremony, which is terribly unoriginal. I could explain why I was not a Satanist and that I would never become one. I expressed my perplexed state by stating that I had encountered a great variety of religious beliefs that did not fit my cultural values but seemed to fortify the goodness and decency of those people -- but that Satanism seemed unlikely to ever do that.
No, you do not get a Jew to participate in a prayer that ends "In Jesus' Name we pray". (Paradoxically practically any Jewish prayer is compatible with Christianity). No, you treat Mohammed with kid gloves. You do not contend that Buddhism is absurd. You do not ridicule the Book of Mormon. You do not demand that students deny the existence of God or tell them that if they fail to believe as you do that they will burn in Hell.
A public school must accommodate a variety of religious beliefs, not including those that happen to be a majority view or somehow fitting the mainstream. It must accommodate religious views that are inconvenient and strange. It is not the place for missionary efforts or attempt to 'correct' the religious beliefs of students.
