Well, considering that Junpei nukes one of them with a Agidyne spell when the said person has a Persona immune to Fire, I guess we just chalk it up to Gameplay and Story Segregation (Warning: Slain does not take any responsibility for any time wasted on TVTropes as a result of this link).
Oh, and after looking it up on Wikipedia, it's entirely possible that [Revolver Jesus] uses bullets with non-deformable material cores. Since deforming bullets to increase surface area is all bulletproof vests do, it is entirely possible for a bullet with such a core to go right through. I also remember stories of bulletproof vests failing even at mid-to-long range.
I don't remember the cutscene too well, so eh.
