In fact, I think they have violated the Geneva Convention, Protocol II (8 June 1977), as to American citizens, which I well know from my own war crimes trial experience where former government officials are charged under the Geneva Convention with war crimes for not protecting the people they were sworn to protect:

Art. 7
1. All the wounded, sick and shipwrecked, whether or not they have taken part in the armed conflict, shall be respected and protected.
2. In all circumstances they shall be treated humanely and shall receive to the fullest extent practicable and with the least possible delay, the medical care and attention required by their condition. The shall be no distinction among them founded on any grounds other than medical ones.

Art. 8
Whenever circumstances permit and particularly after an engagement, all possible measures shall be taken, without delay, to search for and collect the wounded, sick and shipwreck, to protect them against pillage and ill-treatment, to ensure their adequate care, and to search for the dead, prevent their being despoiled, and decently dispose of them.

There is also the Universal Declaration of Human Rights, Art. 25(1) (1948):

Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.

More about this later. I'm just getting started.
