Exactly. I've worked for cops (taking care of police orphans/half orphans) for three summers when I was younger.

They're ultimately good guys (well, as good as any random guy is, not worse not better) but their experience of the society turns them into distrustful, clanic semi-sociopaths. The fear of other people reactions is ingrained.

The one that marked me is that they were afraid of local teens chatting up with our teens and learning they were police children, and passed that fear to all kids by saying extremely weird and violent shit they probably believed, but were ultimately lies. They wanted the children, most of them orphans, to avoid talking to regular kids outside of the camp, and lie if they did.

Not bad guys inherently, but clearly fucked up by their job.
