The Sinner and the Sandman - S5-E2
Factual error: Members of The Salvation Army do not gamble and do not buy lottery tickets.
I Only Have Eyes For You - S2-E19
Factual error: In the episode 'I Only Have Eyes For You', during the flashbacks to 1955 James and Grace dance, and James later shoots himself, to the song 'I Only Have Eyes For You', which wasn't released until 1959. (00:18:20 - 00:26:50)
Factual error: Whenever the killer (always dressed in black with a balaclava disguising his/her identity) uses a knife, the blow invariably is an overhand strike. However, a knife in a downward thrust quite frequently simply skids off the overlapping ribcage of the victim.
Yukiyasha Legend Murder Case: File 3 - S2-E16
Factual error: Kindaichi begins his revelations at 4:10, and the time gradually shifts at 4:20 (which is a bit much for the amount of information revealed and the dynamics of the conversation, but okay). He then moves to the river, which is a couple minutes away from the house by car, to deliver the rest of his speech, and the sun dawns at that moment. It's a Japanese winter with -20 C°, the sun surely wouldn't rise at 4 AM. (00:06:30 - 00:12:00)
Factual error: In the scene where T.J. Is explaining the formula to Mo that is written on the board, the right side of the equation (x-1)^2 is wrong. It should be x^2 - 2x + 1, not x^2 - 2x - 1 when expanded. Also, at the start of the scene with the formula, the coach who is teaching the class states he wrote it, and then it is assumed T.J. came up and finished solving the equation, but the writing is exactly the same.
