Our legal system assumes that a defendant is innocent until proven guilty beyond a reasonable doubt. But what constitutes a reasonable doubt? Law professors Ariel Porat and Alon Harel suggest that an “aggregate probabilities principle” might help to determine whether an accused party is innocent or guilty.

Suppose we’ve decided that the evidence must indicate a probability of 95 percent guilt before we’re willing to declare a defendant guilty. Mr. Smith is accused of two separate crimes, with a 90 percent probability of guilt in each case. Under the 95 percent rule he’d be acquitted of both crimes. But Porat and Harel point out that there’s a 10 percent chance that Smith is innocent of each crime, and aggregating the probabilities gives a 0.10 × 0.10 = 0.01 chance that Smith is innocent of both — that is, there’s a 99 percent chance that he’s guilty of at least one of the offenses.

On the other hand, consider Miller, who is also accused of two different crimes. Suppose that the evidence gives a 95 percent probability that he committed each crime. Normally he’d be convicted of both offenses, but aggregating the probabilities gives a 0.95 × 0.95 = 0.9025 chance that he’s guilty of both offenses, and hence he’d be acquitted of one.

In A Mathematical Medley (2010), mathematician George Szpiro points out that this practice can produce some paradoxical outcomes. Peter and Paul are each accused of a crime, each with a 90 percent chance of being guilty. Normally both would be acquitted. But suppose that each was accused of a similar crime in the past, Peter with a 90 percent chance of guilt and Paul with a 95 percent chance. Accordingly Peter was acquitted and Paul went to prison. But historically Peter has now been accused of two crimes, with a 90 percent chance of guilt in each case; according to the reasoning above he ought to be convicted of one of the two crimes and hence ought to go to jail today. Paul has also been accused of two crimes, with a 0.95 × 0.90 = 0.855 chance that he’s guilty of both. He’s already served one prison term, so the judge ought to acquit him today.

Szpiro writes, “Thus we have the following scenario: in spite of the evidence being identical, the previously convicted Peter is acquitted, while Paul, with a clean record, is incarcerated.”

In 1944, a bizarre criminal assaulted the small town of Mattoon, Illinois. Victims reported smelling a sickly sweet odor in their bedrooms before being overcome with nausea and a feeling of paralysis. In this week’s episode of the Futility Closet podcast we’ll pursue the mad gasser of Mattoon, who vanished as quickly as he had struck, leaving residents to wonder whether he had ever existed at all.

We’ll also ponder the concept of identical cousins and puzzle over a midnight stabbing.

Intro:

Enterprise, Ala., erected an $1,800 monument to the boll weevil.

In the late 1930s, a plaster mannequin named Cynthia archly toured the New York social scene.

When William Harrison disappeared from Campden, England, in 1660, his servant offered an incredible explanation: that he and his family had murdered him. The events that followed only proved the situation to be even more bizarre. In this week’s episode of the Futility Closet podcast we’ll describe “the Campden wonder,” an enigma that has eluded explanation for more than 300 years.

We’ll also consider Vladimir Putin’s dog and puzzle over a little girl’s benefactor.

Intro:

In 1921, Pennsylvania surgeon Evan O’Neill Kane removed his own appendix. (Soviet physician Leonid Rogozov did the same 40 years later.)

John Cowper Powys once promised to visit Theodore Dreiser “as a spirit or in some other astral form” — and, according to Dreiser, did so.

Podcast Episode 124: D.B. Cooper

https://archives.fbi.gov/archives/news/stories/2007/december/dbcooper_123107

In 1971 a mysterious man hijacked an airliner in Portland, Oregon, demanding $200,000 and four parachutes. He bailed out somewhere over southwestern Washington and has never been seen again. In today’s show we’ll tell the story of D.B. Cooper, the only unsolved hijacking in American history.

We’ll also hear some musical disk drives and puzzle over a bicyclist’s narrow escape.

Intro:

In 1973, Swedish mathematician Per Enflo won a goose for solving a problem posed 37 years earlier.

Established in 1945 by a sympathetic actor, the Conrad Cantzen Shoe Fund will reimburse working artists $40 toward a pair of shoes.

Rotary Jails

https://patents.google.com/patent/US244358A/en

Architect William H. Brown had a curious brainstorm in 1881 — a jail in which moving cells shared a single door:

The object of our invention is to produce a jail or prison in which prisoners can be controlled without the necessity of personal contact between them and the jailer or guard. … [It] consists, first, of a circular cell structure of considerable size (inside the usual prison-building) divided into several cells capable of being rotated, and surrounded by a grating in close proximity thereto, which has only such number of openings (usually one) as is necessary for the convenient handling of the prisoners.

The cell block, supported by ball bearings, could be turned by a single man with a hand crank. While it had a certain efficient appeal, in practice the jail proved dangerous, crushing prisoners’ limbs and raising concerns about safety during a fire. The last rotary jail was condemned in 1939; the only surviving example is in Crawfordsville, Indiana.

The Oddfather

https://commons.wikimedia.org/wiki/File:Gigante_bathrobe.jpg

Vincent Gigante, head of the Genovese crime family from 1981 to 2005, feigned mental illness for 30 years in order to throw law enforcement authorities off his trail. Beginning in the 1960s he could regularly be seen shuffling around his Greenwich Village neighborhood in pajamas, a bathrobe, and slippers, mumbling to himself, and quietly playing pinochle at a local club. His lawyers and relatives insisted he had become mentally disabled, with an IQ of 69 to 72.

But informants told the FBI that during this time he was really leading the wealthiest and most powerful crime family in the nation and a dominant force in the New York mob.

At arraignments he appeared in pajamas, and psychiatrists testified that he had been confined 28 times for hallucinations and “dementia rooted in organic brain damage.” “He was probably the most clever organized-crime figure I have ever seen,” former FBI supervisor John S. Pritchard told the New York Times. Mob rival John Gotti called him “crazy like a fox.”

It wasn’t until April 2003, in exchange for a plea deal, that he acknowledged that the whole thing had been a con to delay his racketeering trial. His lawyer said, “I think you get to a point in life — I think everyone does — where you become too old and too sick and too tired to fight.” He died in prison in 2005.

Expecting

During a visit to the Colt firearms factory in Connecticut in 1995, English sculptor Cornelia Parker was captivated by the recognizably gun-shaped casts of metal produced early in the manufacturing process. As blank casts they had none of the capacities of working weapons, but “in one further step, a hole drilled, a surface filed, they would technically become firearms.”

Fascinated by this transition, “I asked the foreman if I could possibly have a pair of guns at this early stage in the production, and if he could give them the same finish that they’d get at the end of the process,” she wrote later. “Amazingly, he agreed, and they became Embryo Firearms, conflating the idea of birth and death in the same object.”

Ironically, as she was leaving America, customs officials discovered the casts in her luggage and “an argument ensued that perfectly reflected the questions raised by Parker’s work,” writes Jessica Morgan in Cornelia Parker (2000). “The American Customs department insisted that Embryo Guns were weapons, while the police department, in Parker’s defense, argued that they were harmless metal forms and Parker was released from questioning.”

Crime and Punishment

German playwright Ernst Toller was arrested for socialist activities in 1919. His 1937 collection of letters from prison, Look Through the Bars, includes this memory:

Stadelheim 1919

Dear ——,

We are a hundred men here in prison, separated from our wives for months. Every conversation between any two men always ends in the same way — women.

The high walls prevent any view. Within the walls is a small hut. It was, we heard, some sort of wash-house, which was not used. One day one of us saw that the shutters of the hut were opened. He saw two women at work. One stayed in the wash-house, the other went away and locked the door. Soon we knew all. The two women were a wardress and a prisoner, who was to be released in a short time. She had been sentenced to eight years’ imprisonment for child-murder. She had already served five years; in a few weeks’ time she was to be pardoned.

It would be too complicated to tell you how we contrived to exchange notes with the girl. First playful and harmless ones, then feverish, passionate and confused ones. Everything which, in that closed-in existence, had come in dreams, wishes and fantasies went out to that woman. One morning she gave us a signal. We were to stand near the window at a certain hour.

Impossible to describe what happened. The woman opened her dress and stood naked at the window. She was surprised and taken away. We never saw her again. But we learned that the pardon had been annulled.

Never has a woman moved me so much as that little prisoner, who, in order to make men happy for a few seconds (in a very questionable way) suffered with unsophisticated wisdom three more years in prison.
