I feel like there are a lot of plotholes in the Fallout series in general. For example, when they mention that Albert Cole would've been something similar to a lawyer, I feel confused as I thought it was supposed to be a Vault-Tec archive or something like that. Besides, wouldn't it make sense that a lawyer would be a profession that wouldn't even be known anymore? Also, when you look at Vault 13, there's nothing like a courtroom in it. Sure, there's a few rooms where I COULD see a court hearing being held (Overseer's Office, Cafeteria, etc.), but other than that, no courtroom.
Either way, most of the Vault Security Patrols (for the Vaults that HAD them) all tend to be extremely hostile towards lawbreakers, so there wouldn't be any point in having a lawyer around in the first place.
I mean, just look at how Vault 101 flipped when James left the Vault. If they were to kill the Lone Wanderer, there would be no point in having a lawyer.
Sorry that this is a bit irrelevant to the thread, but this is a plothole that has sat with me for over a year now, and I really thought it was a good opportunity to let it free.
