2 point's:
1) At least one medal of honnour has been won by a medic defending his patients.
2) Only the civilised world observes the laws of war. The bunch that we are up against at present don't. They expect to be treated according to the geneva convention and the laws of war if captured, but claim the right to treat any serviceman who falls into their hands any which way they see fit.

I'm not going to go into a rant about the subject as this is not the right place, but I will note that we are effectivly back to 18th & 19th century colonial warefare. And those rules apply.
