criminals demand immunity:

‘$10 billion UN-linked climate change fund wants immunity from prosecution
The Green Climate Fund, (GCF) a United Nations-affiliated piggy-bank  intended to finance climate change projects around the world, is determined to win sweeping U.N.-style immunities from prosecutions for its global operations–even though  the U.S., its biggest contributor, opposes the idea, and the U.N. itself says its own diplomatic immunities can’t cover the outfit.
If the GCF succeeds in its broader negotiations, not only billions but eventually trillions of dollars in climate funding activities could fall outside the scope of criminal and civilian legal actions, as well as outside examination, as the Fund, which currently holds $10 billion in funding and pledges, expands its ambitions.
The shield would cover all documentation as well as the words and actions of officials and consultants involved in the activity documentation—even after they move on to other jobs.
