Quick Note on Outlaws

I've just come across this update to the Butch Cassidy story I wrote about a few weeks ago, which claims that the writer of Cassidy's biography was not, in fact, Cassidy himself, but an impostor who had pretended to be Cassidy and was in prison at the same time as Cassidy. It appears, then (according to this information), that instead of Cassidy impersonating William Phillips/Wilcox, Phillips/Wilcox actually spent most of his life impersonating Cassidy impersonating Phillips! It sounds, perhaps, as though Phillips/Wilcox might be a better topic of study in terms of fraud than Cassidy is, and more or less debunks the theory that Cassidy did not die a violent death in South America.
