This is the kind of stuff that would've gotten me suspended or even expelled had it been implemented when I was a student because I would've purposely disobeyed it in a flamboyant and impossible to ignore way and gotten others to do so with me. I knew as a kid that even if my parents didn't care about school policies (which they often didn't), somebody else's would and would contest them. With modern measures of "safety" students are subjected to more and more restrictions, and it seems they're becoming more passive as a consequence. That may actually be the intended result. But it seems to be harming students more and more as they seem less inclined to oppose obviously stupid policies and decisions. Later in life that passivity towards authority will harm them as others take advantage of or even abuse them in a professional setting.
