Plot hole: The police are on the trail of a known psychotic and mass murderer. When they turn up at the house of the mother superior, it's evident Ricky has been there, as the door has been cut open and kicked in. There is no way the other nun would have been able to freely enter the house without police escort, or even get out of the police car, as Ricky had not been located and apprehended. The house is a potential crime scene and she would not have been allowed in.
Plot hole: In the flashback scene from Part 1 when the two cops go into a house after seeing a Santa Claus climbing into a window who turned out to be a dad visiting his daughter, we hear Ricky say "Daddy almost got his present early," how would Ricky know about this scene?
Suggested correction: He would know about it because he was there.
