Saw IV

Plot hole: Rigg plays the woman's tape without rewinding it and it starts at the start of the tape. The woman would have listened to the tape to know the knife was under the TV. But why would she rewind the tape to the beginning after? (00:27:00)

Plot hole: When Rigg is listening to the tape in the first hotel room, the tape instructs him to wear the pig mask in order to conceal his identity from the hotel cameras. Rigg wasn't wearing the mask when he entered the hotel, so putting the mask on after the cameras have already seen his face would do absolutely nothing to conceal his identity. (00:36:00)

Visible crew/equipment: Several times in the movie you can see a stunt double for Donnie Wahlberg, like when he tries to hang himself. Art runs over and there is a wide shot focusing on both of them. No slo-mo required, but you can see it's a stunt double.

Jigsaw: Hello Brenda. I want to play a game. An officer will try to save you. If he is successful, then your game begins. This man will use these photos to sentence you for your crimes and the only way to stop him is tapped underneath the TV. Let him save your life, and accept your fate to rot in prison, or kill him... and guarentee your freedom. Make your choice.

Question: I don't understand why Hoffman isn't electrocuted at the end. He was connected to high voltage cages and his feet came under water, so how did he and/or Jigsaw plan so he wouldn't be electrocuted under any circumstances?

Answer: The chair wasn't actually electrified. It was just made to look that way in order to hide his involvement in the game.
