True, but when all the LEOs stand by and treat a death as natural maybe it wasn't really murder to begin with.
From Minor v. Happersett:
"The Constitution does not, in words, say who shall be natural-born citizens. Resort must be had elsewhere to ascertain that. At common-law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives, or natural-born citizens, as distinguished from aliens or foreigners. Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents. As to this class there have been doubts, but never as to the first."
The de facto practice of calling such persons "citizens" may indeed have become not a homicide, but with such ambiguity still present, no sane person extends that to obviate the Presidential qualification.
We can tolerate little crimes at the fringes, but not when they affect the entire nation.
The Kenyan was not qualified, no matter where he was born.
