Factual error: During the interrogation room scene, it is very bright in the room looking into the interrogation room, and it is dimmer inside the interrogation room. Although this would mean that the suspect would be able to see everyone watching as for him to just see a reflection, it needs to be bright his side, and darker the other side. True the glass could have been slightly reflective on one side, but the laws of optics still apply.
