If committed as part of a Saudi government policy to murder migrants, these killings would be a crime against humanity

And if the government was clever enough never to make it "policy"? Does that somehow change the number of people they've killed or the nature of their crimes?

It feels like they make these vague definitions up with loopholes the sizes of countries so that no one ever has to actually do anything to stop these crimes from happening (because those in power profit too much off them)..
