Also that scene was darkly hilarious, with Marty coming downstairs and fixing a cup of coffee, while Rust is drinking whiskey straight and looking into whatever that thing is, at like 7:00 AM….And Marty's line to the dude is prison, "Gotta be tough, living with somebody spoutin’ insane shyt in your ear all day long"….Michael Mann had to be an influence on that final shootout, it's frenetic, frenzied, claustrophobic tension…..When Rust is trying to keep the whole thing from spiraling out of any semblance of control that may have existed, 'don't fire', don't fire'….I'm also dead at all the commentary here regarding the haphazard, idiotic planning of the Crusaders, the thing is though shyt happens like that ALL the time, maybe not running gunfights in what looks like Juarez slums, but violent, gruesome brutal crimes related to drug trafficking and the lure of fast money, fueled by adrenaline and schedule II substances.
