No, we require extensive training, and re-training, of doctors. On top of that, they need malpractice insurance, which balloons for the individual if they're royal fuckups. They aren't demonized, they're held accountable.
Demonization is a consequence of bad behavior combined with radical unaccountability.
>Yeap, there are bad actors in the police just like in all other walks of life.
Irrelevant. It's evidence that refutes your earlier claim that police can not legally "kick the shit out of you". They can. Dismissing them as "bad actors" doesn't change that fact.
I'd take it a step further after having read the article associated with that horrifying picture. Two of the officers were found not guilty. The third had charges dropped. This isn't just "bad actors", this is bad actors with the backing of the court system.
