Ah, the trope of the interrogation room with the solitary swinging bulb. I'm pretty sure police departments can afford light bulbs, and that police officers would rather be in the presence of a known or suspected criminal with some adequate wattage so they can actually see the criminal. But the trope persists, I just saw someone in a TV show last month interrogating someone in a darkened room. Actually, they were talking to the character in the lobby, then the boss came over and told the officer to 'take him to the interrogation room!" After the commercial, they were in a dimly lit closet-sized room with a single hanging bulb. Was there something wrong with simply continuing the conversation in the well-lighted lobby? Are all criminals afraid of the dark or something? Wouldn't the interrogation be better if they could see the perp's expression?
Oops, almost forgot! SUPER CHICKEN CLOSEUP GET!!!
