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 1, "Turnabout Target".
In this video, I get confused when the game starts talking about two identical guns. Turns out that Knightley's gun is clean. The gun found in the trash is the one used to kill Rooke.
Edgeworth realizes that Knightley must have switched his gun with the other gun, in the brief moment that he had all the evidence. At the same time, he put an extra bullet in the gun, to make it seem like it only fired two shots, not three. Edgeworth decides that, if Knightley's fingerprints are on the extra bullet, it proves he switched the guns.
