I respect your view, however I believe from what I've read (from a number of sources) that this is a case where students, members of the community, the administration, and members of law enforcement that have all shared their opinions and reactions, have reacted without actually sitting down and talking things through. This is obviously a very important subject to many people, and in the current environment of quick, emotional reactions, and the use of social medial, it has taken on a life of its own. The student body of many schools have taken a huge jump into social causes, and rightfully so. The principal reacted in a way that protected the students and football players/coaches, while addressing the pain of many in the community. Is it an over-reaction? Maybe. Is it better than having said nothing, or saying something that does not recognize the views of many in the community? Not sure. Either way, the link you share has some valid points, however I don't believe it represents the principal's entire message to the community. It would be better for people to read his full message, take time to hear from all interested parties, and move forward, than to simply read one article, watch only the interview on Tucker Carlson, listen to only the views in the article that you posted, or hear only from those that support the BLM position. It's also important, I think, to realize that ANY symbol (in this case a blue line flag) can be interpreted just about ANY way, by anybody. My son is a 1st responder, and to him, the blue line or red line flags have always meant showing respect to those that have lost their lives helping others in the communities they serve, nothing more.
