This movie seems to weave a lot of fake into it's story-line... I can not find where McVeigh visited some Richard Snell in prison at all. That seems to be fabricated just like Tim's girlfriend "Cindy" in the story. Far as I can find, he didn't have a girlfriend (past High School days) and claimed to not know how to talk to them. Who was the Fredrick person ?
The dialog/script in the movie is wonky, like any gun person (especially a decorated top shooter in the army) would ever call a handgun magazine a "clip". Only Hollywood does that, certainly not a gun enthusiast that travels in gun circles and cherishes the 2nd Amendment.
How about the scene where the movie protrays Tim as upset over an encounter with a black fellow, and plots to shoot him... I can't find that in any fashion, the film seems to make up stuff as it goes along...
What we do know is Tim was a person that kept to himself for the most part and was laconic with others. This is portrayed excellently in the film and that he bombed a Federal building... that is about all this flick got right... We don't get to see him at Waco being part of the upset folks.
This movie is as much fiction as it is non-fiction, thus why I rate is so low... If you wanted to paint a picture, at least use crayons from the correct box to paint that picture.
