From your link:
Crimes against humanity are not codified in an international convention, although there is currently an international effort to establish such a treaty, led by the Crimes Against Humanity Initiative.
There is no authoritative codification of Crimes Against Humanity.
Of course, I suppose one could run to the ICC with accusations of it. See if you can get them to prosecute and punish.
There is no authoritative codification of Crimes Against Humanity.
In my above post, there was listed several examples of what constitute a crime against humanity. That's why the call it crimes (plural) against humanity, genocide being just one of them.
There's no point in playing semantical games just to win an argument on the internet.
These people are working up a case for 'crimes against humanity'. Whatever the actual unlawful acts are, they will qualify as a 'crime against humanity' as well as the actual crime (i.e. genocide, unethical experimentation on humans, etc).
I expect they will file in some type of international court. I don't know how international law works or doesn't work in the U.S. court system.
Do you like to argue just to argue?
