EDIT: this one
just unlocked after doing it again to someone later in the game
This is actually news. The fact that Ghost Interrogator unlocked at a second opportunity means the game understands the achievements were not awarded. This means, most likely, that you will not have to play the game over again. You can simply load a save file before the achievement conditions were met and try again. If at all possible, try to do something a little different so it's less likely to duplicate something that may have caused the game to glitch.
