In some ways that is the most staggering thing of all. They assaulted the man and did horrible things against his will, and now they're attempting to charge him money for the privilege?

That's actually sort of common in the U.S.'s insane healthcare system. You are liable even for health procedures you didn't request, if they were performed on your body. This may be due to an emergency (ambulance took you to a hospital you never asked to go to), due to law-enforcement intervention, whatever. Free markets!

That's guaranteed to make the jury quite a bit less sympathetic to the doctors when this case goes to trial.

I couldn't believe that when I read it. If anything, they should be billing the police, considering they were the ones who requested the procedure.

Maybe they're hoping for some coverage from the malpractice insurers?

Not that I think that'll get very far, perhaps another lawsuit or 5 to try to force them, but if they don't bill the guy they wouldn't have a claim against them to begin with, I'd suspect.
