Let see who is the IDIOT here.
First of all in the US Law we have no category of GRAVE as you described like a Moron. Of course you would not know that because you are an INDIAN MORON.
We have categories like Misdemeanor and Felony.
The charges against the Devyani are committing a Felony.
Under Geneva Convention Consulars who commit Felony outside of her official duties have no Immunity against ARREST and Conviction.
Check the category under Consular in the link I am providing you below and wasting my time to educate an INDIAN MORON like yourself.
let me quote you the Geneva convention to educate a MORON like yourself:
