Arglefumph plays a fan translation of the second Miles Edgeworth game, only released in Japan. The game's full title is "Ace Attorney Investigations: Miles Edgeworth: Prosecutor's Path". This is Episode 2, "The Imprisoned Turnabout".
In this video, we use video analysis on the security footage. It turns out this is NOT a video of a dog attacking Knightley. Rather, it is Jay Ehlbird, disguised as a guard, being attacked by his polar bear. And that's weird, because it doesn't match with the timeline at all.
It turns out that the timer on the camera went out for three hours.
