Look here’s the thing:

Almost nobody who talks about qualifies immunity knows what qualified immunity actually is, but more to the point, there is one serious difference between the doctor v police example…one is working for the state, the other is (usually) not a government worker and suing a doctor for doesn’t mean you can’t also sue the hospital, in fact that is common.

Qualifies immunity applies to government workers (not just police; teachers, DPW workers, and so forth as well).

They are acting on behalf of the state. This also means the government, which they are acting on behalf of, is who is responsible (and importantly, if the person is acting against the law or policy of the government, then they don’t qualify for said immunity)

For whatever reason this conversation constantly forgets that police departments are very literally a part of the local government. Like how when people get upset about someone getting arrested for something, nobody spends two minutes remembering that the cop doing it isn’t the one making the law or ordinance like on their own.
