I’ve been in a similar situation where some agents from the anti terrorism brigade came to my door. Sometimes you just have to shut up and work with them how they see fit.
Nobody was body-slammed, nobody was disrespected, nobody was being held longer than necessary or with excessive force.
This isn’t a situation to turn into hate towards the police. Just get over it and don’t be a fucking asshole.
I think that the commenter lives in a country with for-profit hospitals. In Europe hospitals get subsidized so they all make good money and aren’t driven to pursue profits. Prices are being kept low because of taxes and social health care. There are some for profit hospitals, but not many.
