For this theory about wet works and the movie script to be plausible, then the map referenced which points very specifically to the location of the ranch in Texas where Scalia died would have to have been added to the website for this purpose, don't you think?
Anyway, I looked closer at the website and found the registrar listing to Brian Alpert, who is a big lefty supporter and Trump hater, at least according his twitter. Smithsonian, so no surprise there I guess. Maybe I'm digging an empty rabbit hole, but I wonder what the chances are of the domain owner being directly involved in posting that map to the website for this purpose?
