Yeah, near the end of the episode when they flashback to the two cops in Alcatraz back in '63, the older one asks the younger one his name and it was the same as weird FBI guy in the present.

Are you talking about the 2 patrol cops that Jack shot when he was outside the Key guy's house? I don't think cops on patrol normally wear body armor But yeah, when they were looking for OCD sniper dude, they should have been wearing armor. Plus, I find it pretty bizarre that when Lucy got shot in the chest that she didn't die. A chest wound like that from a rifle should have killed her.
