This one caught my eye earlier in the week. Leaving aside the implications of the "crackdown" element, the list of transgressions - complete with sock inspections - is very similar to the school rules which prevailed when I was a schoolboy - with the exception of mobile phones, which hadn't of course been invented then. Depending on the circumstances, some of the infringements might've been punished by lines (or 'pages' as we had them) rather than a detention - but at the other end of the scale, rudeness towards the staff was likely to have earned you a caning.
It's not entirely clear whether the school *oops, sorry, "community college"* didn't previously have the rules or just wasn't enforcing them. But it's hard to actually find fault with a clear basic framework of what is regarded as acceptable standards of behaviour, and my mother certainly never showed any sympathy if I was punished for doing something I knew I'd been told not to.
