Ah, you know, it's really, really funny where these rabbit trails begin and end.

First, I was going to just suggest that you not waste too much time on the MLK assassination, since it was faked. In short, take a look at the photos of him in his coffins. Yes, coffins. He's in two different ones.

Then take a close look at this face. He's supposed to have been shot through the jaw with a .30-06 from 75 yards. That is a big cartridge you can drop anything in North America with. There is absolutely no trace of either entry or exit wound on his face.

But then I was surprised Uvalde, with a population of only about 15K had an airport. Turns out it's Garner Field Airport and seems normal enough, except for one of the comments on Google Maps reads: "Better $100 hamburger than T82, great staff, great airport!". Immediate Wayfair vibes?

Well okay... inside joke? But the whole Wayfair thing was both functional and an inside joke, wasn't it? Why can't anything ever be normal? And I checked T82, which is Gillespie County Airport, and found the comment, "They have lots of drinks and snacks available for cheap." They can't just have some very different idea of "cheap", can they?

It was mentioned in the article you linked that Dan Rather met with John Nance Garner, and the airport there is actually named after him. When I looked up his wiki, I found this:

In 1901, Garner voted for the poll tax, a measure passed by the Democratic-dominated legislature to make voter registration more difficult and reduce the number of black, minority, and poor white voters on the voting rolls. This disfranchised most minority voters until the 1960s, and ended challenges to Democratic power; Texas became in effect a one-party state.

Nowadays, we are to believe that Texas is filled with redneck racist Republicans and--more importantly--always was.
