Plot holes! Get your plot holes!
The movie cheats in order to put Devereaux in danger. We are told that Uribe, who had facilitated the photographing of the contents of the red case, had been tortured, revealing Devereaux as a spy. To me, it is not credible that Uribe would have known that. It is not credible that Uribe would have been aware of Devereaux' existence at all, given that they never met.
Oh, I know. Devereaux' friend bumped into him while running away to hand off the film. How incriminating!
