life of david gale

[Geggy]

last night i stayed in and rented this movie. despite bad acting, it was fucking genius but i have some questions to those who may have already seen it. those who havent (whom i would highly recommend), spoiler ahead.....


in the end, the reporter received the tape that was labelled 'this will set you free...' now the tape showed david gale in the set up after what was suppose to look like a lady commiting suicide. from my point of view, it was dave's idea to make it look like a suicide and the lady friend agreed to do it. she put the plastic bag over her head and handcuffed herself. after a certain amount of time he was supposed to rip the plastic bag open but instead he let her die. he was angry at her for not telling about the cancer and got him too attached to her. he also did it for political reason to prove that federal execution is wrong. he had nothing to lose, his life was already screwed. now i have a questoin about the labelling on the tape that said 'this will set you free', did it mean the reporter felt the guilt of arriving the scene minutes too late with the different copy of edited tape what couldve been an important evidence to prove gale's innocence yet the other tape with the labelling showed that he wasn't, she wouldnt be feeling so guilty afterall? am i seeing this whole thing the wrong way and there's a different explanation?
