I hope they realize this— Liability for atrocities under international human rights law, including the Rome Statute, extends not only to the actual perpetrators or direct participants in such heinous acts, but also those who tolerate and condone them, more so incite and encourage them as well as those who do nothing about the prevalence of massive EJKs despite knowledge thereof.
Yes, failure to act, meaning, failure or refusal to investigate and prosecute, and worse do a cover-up such thru barefaced denials or half-baked, prematurely terminated probes, also gives rise to liability.
Sooner or later, the long arm of the law, domestic or international, will catch up with the chief architect of the mass murders and his enforcers and cheerers.
Stop cheering the madman!
