"Racist American Diplomat Alicia Muller May speaks about her Diplomatic Immunity as a ‘Get Out Of Jail’ card. Funny how the US State Department however thinks that Diplomatic Immunity applies only to Consular functions, and not personal actions."
1. If Alicia Muller May has been accorded diplomatic immunity by the United States she cannot be prosecuted under Indian local laws.
2. It is not the position of the US State Department to interrupt the law but the Court.
3. The statement "US State Department however thinks that Diplomatic Immunity applies only to Consular functions, and not personal actions." is entirely inaccurate.
The fact that she cannot visit the US on a diplomatic visa is inaccurate.
However the supposition for her to visit the US on a diplomatic visa after the state department has called for her withdraw will bring US-India relation to an all time low. This supposition is based on the fact that india's foreign department will be willing to ruin its relation with the US in order to appoint her to a position within the Indian government to conduct diplomatic affairs with the US.
