He does resemble him (more like a relative) but the fact remains the guy vanished after giving intel that would have hurt ((them)) so it would be counterproductive for them to hire an actor to hurt their own flag. Besides, there are now 14 (confirmed) dead individuals who "survived" the LV event so I wouldn't be surprised if he is yet another they did away with.
the NRA doesn't need ties to shit. it's the other companies that need them and not the other way around. the NRA is a superpower financially and could easily (alone) fuck up all of those companies combined if it came to a financial battle.
