The main game was good at making it clear where to present the evidence when you found the contradiction. This case really isn't and suffers a lot for it. In one testimony the lie is in three different statements and can be proved with two pieces of evidence, but the game only accepts one combination.

ALSO all the evidence is hilariously absurdly detailed, almost like the aquarium's marketing department knew their poster would be used in a murder trial.

ALSO..... there's no way the orca is happy in a tank that small, come on.
