i think it depends on the place and the public sector, like firemen and dvla workers are both public sector, but neither have the scope for committing crimes against humanity. but people generally dislike the dvla and love firemen.

but then you have ICE who are perhaps doing their job of deporting illegals, but there is probably a good percentage of them who are taking pleasure in being sadistic about it and they have power to abuse.

one example of public sector differences is in the UK, I don't mind the police, they're mostly useless, but when I lived in Russia, the police were the enemy and you didn't want to involve them in anything. They were worse than the cops and the FSB is even worse, carrying out hits on businessmen and basically acting like gangsters. Litvinenko wrote a lot about this and his revelations were what later got him killed.

so it's a mixed bag
