The same happened to Modi, the PM of India, if my memory serves me right. He was banned from entering USA for his deeds, until he turned out to be the head of India. Apparently your only way out is to be the head of your state, if you have done something evil.
Let me clarify some points at the risk of sounding like a Modi supporter. Modi had gone though investigations and was acquitted by the Supreme court of India. It was definitely failure of government mechanism and officials but not state sponsored voilence. " The Supreme Court on Friday dismissed allegations of "larger conspiracy" levelled by Zakia Jafri, widow of Congress leader Ehsan Jafri who was killed in the 2002…
Modi was dismissed. They didn't look into it. He avoided All investigations when it happened and still avoids questioning to this day. No one was punished. No blood money made its way. Nothing.
Many more people died at modi's hands than MBS. There is no comparison.
