Plot hole: In the unedited video footage of the helicopter incident shown to the crowd, the last shot of Arnie getting knocked out is seen from his perspective and as such could never have been filmed by any camera.
Plot hole: When Richards' turbo sled goes through the tunnel along with Weiss' and Laughlin's, the video monitors show all three sleds are traveling through the same tunnel. Richards' sled comes out of the tunnel first, but with the speed the sleds were going and all three in the same tunnel, there wouldn't have been enough time for Richards to be pulled out, and Laughlin would have come out so fast it would have crashed into Richards, ending his running before it even started.
Plot hole: There is no reason for the prison guards to use portable computers in full view of the inmates to input the sonic deadline code. The guards can walk outside of the deadline whenever they need to input the code, or radio the guard on the outside to lower and raise the deadline like they do when bringing the workers out. In fact, this plot hole is compounded by the presence of the guards stationed outside of the deadline with their own computer, which makes the guard inside the deadline completely unnecessary. The interior guard is only there so Weiss has a way to get both the code and a computer, but this prison set-up makes absolutely no sense.
Suggested correction: The point of having a portable on the outside and inside is in the case of an attempted prison break, if one of the computers is taken by the prisoners, the other can be used to prevent the deadline from shutting down. This was actually shown in the prison break scene where Weiss was unable to shut off the deadline with the inside computer was because the guards on the outside one were countering any attempts to close it.
That only explains why there is a guard outside with a computer. There is no reason to have a guard on the inside of the deadline with a computer. There can't be a prison break if there are no guards with a computer on the inside, the inmate's heads will explode if they cross the deadline.
Plot hole: After Richards goes back to his brother's apartment, he is somehow able to shower, shave off his beard and change his clothes despite the fact that the apartment is now occupied by a woman living by herself who would not have any reason to have men's clothes or male grooming products there.
Suggested correction: A similar entry was already added and corrected. Amber tells Richards she has a box of items that the previous owner, who she just learned was his brother, left behind. This box could include clothes and shaving materials. Why she kept the box, we do not know, but probably because she is a nice person and kept the box in case the previous owner or a friend came back to claim the items.
