At a local clinic of a large local hospital where I stop occasionally I see posters, prominently placed, stating that if you need medical services and cannot afford them, that medical establishment is bound by law to provide it for you, despite your inability to pay. Tina can get her surgery for free. The government demands it.
Don't bet on it. I speak from experience when I say that medical care is like many other things. You get what you pay for.
However, when taking out the bad guy, I think the author is injecting a bunch of "would/could happen" scenarios as if they are guaranteed. In being sued for your actions, I think that depends upon many issues. In particular, the state and city you live in.
