Juan Jose Castro.... A close relative of Fidel.....
C'mon.....What pat of "imaginary" don't you understand? I invented that scenario to demonstrate that it's possible that Lee was given the gun in the Theater....
Well, if LHO was set-up, of course, he would have to of been directed to the theater to unknowingly meet a zillion officers for what, not paying the admission? Instead, they should have sent LHO to Ruth Paine's neighbor. Sure, it's miles away but if Lee can do all these impossible tasks you just create another impossible feat.
Getting back to your revolver idea. He had before he left the DSBD. I don't understand why he stopped by the boardinghouse, involved or not, that is the last place I would go
