Plot hole: In his mad dash from the security guard at the Mental Health Facility, Cooper drops about 90% of the file folders he had taken. Yet he somehow manages to hold onto the files for the main people they were photographing earlier in the film.

Plot hole: While planting the suicide gear in the bathroom before Buckley comes in, Cooper tells Josh to tie the rope into a noose as they go to hide in the shower. Josh replies that he doesn't even know how to tie a noose.
