I do not think you may call Mrs. Webb the torilla chip inventor, yes
maybe she was the first to openly mass produce and sell them in the
U.S. It is like calling the Taco Bell guy the taco inventor or Ronald
McDonald the hamburger inventor.

About Pancho Villa, yep he didn't like americans, but only those who
mis-treated and abused mexicans, like mining overlords perhaps?.
Remeber that Pancho Villa made some deals with Hollywood directors to
make movies about him and the mexican revolution.

His assassination is perfectly explainable, he was still to popular
with the people and therefore a threat to the goverment.
