From what was reported of that incident, it seems as though it was an attack (and possible hate crime) perpetrated by kids from another school on the buses frequented by the kids from the JFS. Sounds like it may, or may not, be directly related to the Israeli state's on-going genocide in Gaza or just straightforward racism/antisemitism?
If it were motivated by the attack on the Palestinian people, then you're right, it is of no help whatsoever, but I'm not sure how valuable it is to attempt to analyse it through the prism of how helpful it is.
