Saw IV

Other mistake: In Saw II, Jigsaw shares a story with Detective Matthews about how he attempted suicide after his cancer diagnosis by driving his car off a cliff. We then see Jigsaw pulling a metal rod out of the left side of his stomach. However, no puncture wound/scarring is visible on Jigsaw's stomach when his autopsy is being performed. (00:00:50)

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.
