International Christian Concern, a nonprofit organization that “exists to relieve the suffering of the worldwide persecuted church”, wants the tribe to be charged with murder.
Some Christians aren't just calling him a hero or martyr. They're also calling him murdered and part of an alleged persecution of Christians by Hindus.
Seems to me if there were ever a good case for "stand your ground", the tribe has it.
I can't see how the authorities could possibly identify the guilty person or persons; You cannot charge a tribe with murder, any more than you can charge a family, or a town with murder.
If I am killed in Manhattan, then my family might be really upset, but they are going to have no luck getting the city or state of New York charged with murder. If the NYPD can't identify the specific person or persons who killed me, then all they can do is keep the case open and unsolved.
The same applies here - the law prohibits contact with the Sentinelese, so the police can't interview them (even if they can find an interpreter, which they likely can't). How are they supposed to identify the 'guilty' party - and under what jurisdiction would they determine guilt? India claims territorial possession of the island, but they have never tried a crime committed there, and I would argue that the jurisdiction over the island is held in common by the Sentinalese themselves - so IF they consider this killing to be unlawful, they can take action themselves to bring the guilty to justice. And if they consider the killing to be lawful and justified (which they appear to do), then there is no crime. US law doesn't apply. Indian law arguably doesn't either.
There is no case for intervention in an internal judicial matter for the people of North Sentinel Island by any external jurisdiction. They have signed no international treaties, nor any agreement to accept Indian, British, or any other colonial rule. It's their island, and their law - and while I am not a lawyer, I suspect that international law would respect those facts, and allow them unencumbered jurisdiction over the island - as is required by the Indian law against contact.
While it is a rarity for any modern jurisdiction not to have a law against murder, it would appear that North Sentinel Island is such a jurisdiction, as they are not known to have any code of law at all - The place is a libertarian paradise.
So if any Christian group wants any specific Sentinelese person charged with a crime, they will need to petition the Sentinelese directly. Which they are not legally permitted to do, nor linguistically capable of doing.
Oh dear, what a shame, never mind.
