Off-topic, but there’s a great description of this thinking (that there’s an Out) in the book Homicide: A Year on the Killing Streets by David Simon (of The Wire fame):
Summary
As you read, he leaves the room and returns a moment later with a second detective as a witness. You sign the bottom of the form, as do both detectives. The first detective looks up from the form, his eyes soaked with innocence. “He came at you, huh?” “Yeah, he came at me.”
Get used to small rooms, bunk, because you are about to be dropkicked into the lost land of pretrial detention. Because it’s one thing to be a murdering little asshole from Southeast Baltimore, and it’s another to be stupid about it, and with five little words you have just elevated yourself to the ranks of the truly witless.
End of the road, pal. It’s over. It’s history. And if that police detective wasn’t so busy committing your weak bullshit to paper, he’d probably look you in the eye and tell you so.
…
To illustrate the point, he could hold up your Form 69, on which you waived away every last one of your rights, and say, “Lookit here, pistonhead, I told you twice that you were deep in the shit and that whatever you said could put you in deeper.” And if his message was still somehow beyond your understanding, he could drag your carcass back down the sixth-floor hallway, back toward the sign that says Homicide Unit in white block letters, the sign you saw when you walked off the elevator. Now think hard: Who lives in a homicide unit? Yeah, right. And what do homicide detectives do for a living? Yeah, you got it, bunk. And what did you do tonight? You murdered someone.So when you opened that mouth of yours, what the fuck were you thinking?
Homicide detectives in Baltimore like to imagine a small, open window at the top of the long wall in the large interrogation room. More to the point, they like to imagine their suspects imagining a small, open window at the top of the long wall. The open window is the escape hatch, the Out. It is the perfect representation of what every suspect believes when he opens his mouth during an interrogation. Every last one envisions himself parrying questions with the right combination of alibi and excuse; every last one sees himself coming up with the right words, then crawling out the window to go home and sleep in his own bed. More often than not, a guilty man is looking for the Out from his first moments in the interrogation room; in that sense, the window is as much the suspect’s fantasy as the detective’s mirage.
The effect of the illusion is profound, distorting as it does the natural hostility between hunter and hunted, transforming it until it resembles a relationship more symbiotic than adversarial. That is the lie, and when the roles perfectly performed, deceit surpasses itself, becoming manipulation on a grand scale and ultimately an act of betrayal. Because what occurs in an interrogation room is indeed little more than a carefully staged drama, a choreographed performance that allows a detective and his suspect to find common ground where none exists. There, in a carefully controlled purgatory, the guilty proclaim their malefactions, though rarely in any form that allows for contrition or resembles an unequivocal admission.
In truth, catharsis in the interrogation room occurs for only a few rare suspects, usually those in domestic murders or child abuse cases wherein the leaden mass of genuine remorse can crush anyone who is not hardened to his crime. But the greater share of men and women brought downtown take no interest in absolution. Ralph Waldo Emerson rightly noted that for those responsible, the act of murder “is no such ruinous thought as poets and romancers will have it; it does not unsettle him, or frighten him from his ordinary notice of trifles.” And while West Baltimore is a universe or two from Emerson’s nineteenth-century Massachusetts hamlet, the observation is still useful. Murder often doesn’t unsettle a man. In Baltimore, it usually doesn’t even ruin his day.
Simon contrasts the above with what people who know their business do:
For that reason, the professionals say nothing. No alibis. No explanations. No expressions of polite dismay or blanket denials. In the late 1970s, when men by the names of Dennis Wise and Vernon Collins were matching each other body for body as Baltimore’s premier contract killers and no witness could be found to testify against either, things got to the point where both the detectives and their suspects knew the drill:
Enter room.
Miranda.
Anything to say this time, Dennis?
No, sir. Just want to call my lawyer.
Fine, Dennis.
Exit room.
