I believe that you have not read carefully either the article or my posting. I have not said anything about the police. I have quoted directly from the article exactly what the school management said. It is the school management who has said that the guilty party in this incident is neither the school nor the surveillance equipment, but the student who "was holding his musical instrument like a rifle". (This does not even take into consideration that there may be legitimate reasons for holding a musical instrument like a rifle, e.g. for checking it for defects or dirt.) It is also the school management who implied that they will reprimand any student for "pretending to have a weapon". I do not know how you played as a child, but "pretending to have a weapon" is certainly an exceedingly common behavior, perhaps more so in countries where people would never think about using true weapons.
