I've not much to add here but best of luck with dealing with this situation! I imagine there's lots of us on here looking forward to the day we can introduce our kids to the hobby and none of us would want to have a chat with social services as a result. It feels like an overreaction in the schools part to me. Unfortunately some people just don't like guns and they evoke in them an emotional response in such people. Best of luck mate, I hope you get it sorted 👍
