Try to explain 10 to HR...
Here HR people can get easily overzealous over very small "infringements" (I had to discuss a couple of times because I left the company phone in the car and had to get it - it takes two minutes but if you exit for such time - of course using the badge - they make you spend a 15m permission!), but try to put big ones under the carpet, because usually the culprit goes whining to the nearest unions representative and HR doesn't want any trouble with unions...
Thereby you see the silly minutiae SS-like enforced, while big security and work issues becomes just, "well, we asked him/her gently to be more careful next time..." - and I'm told I have to learn to treat people, and don't report them if I can avoid it (after all, if then something very bad then happens and becomes a big trouble, the responsibility becomes mine, not HR...)
