unfortunately a capitalist society doesn't function after what's ethical, it functions after what's financially rewarded. in the US legal system, buying a desired testimony rewards all parties involved. thus buying testimonies is an established foundation of the system. everyone working in a sector rely on it being the way it is right now, which is corrupt and unfair. if the system ceased being corrupt then the entire system would collapse. uneven judgment relying on unfair counseling relying on corrupt witnessing and so on. remove one and all other functions which have built around it won't function anymore. this expert witness doesn't really have a choice if they're to participate. to pad their resume and have a chance to exist they have to conform to "the way things are done" i.e. accepted legalized bribery. just the same as with all other sectors and industries

He saw that the driver was a black man with a beard and a mustache." That was the description given about the two people. The entire probabilistic argument presented was heavily based on the probability of a _couple_ matching those six requirements. *Where in the accusing descriptions does proof come up that the two people in John Bass' view were even a couple to start? If we assume John saw the two correct people, he saw the robber and her getaway driver. That does not make a couple.* I feel that was incredibly glossed over in the courtroom, almost more so than anything else.

Yeah he kinda skipped over the actual prosecutors fallacy. The probability introduced in court was the probability of a *random* couple matching whatever parameters they set out. But you can't then flip that to determine the probability that this *specific* couple committed the crime, which is what they did. Even with odds of 1/12,000,000 there's so many people that it's likely there are multiple couples in the area fitting those parameters. And if there's Ex. 3 couples that match those parameters, then the odds this specific couple committed the crime is actually only 33%.

The fallacy is assuming there's an actual correlation between the two without having to consider the population size. Imagine you win the lottery and I claim that you must have cheated because the odds of a random person winning the lottery were 1/1,000,000. That's the same kind of logic, and it's obviously a dumb argument because it's ignoring how many people entered the lottery, which is what really determines how likely it was that there would be a winner at all.

Your last two lines were brilliant! I had no idea that math was used to convict people in courts. Thanks for the video, it's really making me think

There's two MAJOR issues I have with this story and neither of them have anything to do with the math. 1. The woman who was robbed only said that she saw a blond woman. A completely different witness pointed to a blond woman in a pony tail getting into a yellow car with a black man. It is entirely possible that the two witnesses saw two entirely different blond women. There's no reason to assume that a woman with a ponytail, a yellow car, and a black significant other was even related to the crime since the victim never described any of those details. In fact it's entirely possible that the man was either knowingly diverting attention away from his accomplice or unknowingly spotted an entirely different blond woman in the area and assumed she was the same blond woman the victim saw. Blond is such a common hair color that it would be extremely easy for multiple witnesses of the same crime to give entirely different descriptions of who they believed the blond woman to be. 2. It makes absolutely ZERO sense for the woman they believed to have actually committed the crime to serve less time than the man they believed to be her accomplice. I don't know if it's race related, gender related, or both but I looked it up... The sentence for aiding and abiding is 3 to 10 years depending on the severity of the crime so his sentence was accurate. He would of only gotten 3 years anyway even if the case hadn't been over turned. The sentence for theft is 3 years, the sentence for assault is 10 years so the woman should of been looking at 13 years in prison. For her to get LESS than 3 years for assault and theft means she couldn't have already served her full sentence. I think this is a gender related thing cause it's pretty common for women to serve less time than a man would be for the same crime. That's the only reason why she could have served her time in less than 3 years when she actually should have been sentenced to 13 years. It's also possible for a sentence to been extended or reduced based on the person's behavior while in prison but that would in itself be a process of overturning their original sentence.

While the math is bad (or more exactly, the numbers used in it), there is a much much *much* larger issue with the trail as you described it! The profile was compiled by using three witnesses to things that may be completely orthogonal! The guy from the gas station might be talking about an entirely different couple than the man at the alleyway, making the color of the car irrelevant altogether. Combined with the notion that you might want to commit a robbery in not-your-own neighborhood makes it all the more likely that they were in fact *not* the same couple as the couple at the gas station.

The first two parts of the Collins Test are literally just do math properly, and the other two are don't create random garbage based on whatever numbers you have.

This seems like it’s just about the most ridiculous mistrial I’ve heard of. The argument is as good as “If someone won the lottery in the state this is better than any other evidence that this person is guilty.” It’s entirely nonsensical.

Great presentation. I teach several courses in data analysis and concur completely with you. The very fact that they excepted magic numbers as evidence just boggles my mind.

The probability question the prosecutor was answering was "if you pick a random person, what are the chances they satisfy all these conditions?" when the actual question to be answered is "What's the probability the lady of this couple is the thief?" That's when, should the numbers be right, we get a much clearer idea of what we're dealing with. I believe probability like that can be used as a reason to call people for questioning but definitely NOT as evidence

​@@charlieanderson5490 Fingerprints are also being misused lots of times. The probability of two people having the same fingerprints is irrelevant, what counts if the likelihood of an expert telling apart different fingerpint impressions, moreso when those impressions can be partial, faint or degraded. Some studies (ones based on exonerations of previously convicted people based on fingerprints and others based on testing experts with random sets of fingerprints) have shown that the average expert has a 2/3 chance of getting it right.

In some cases it would really be better to let a guilty person get away with their crime, than risking to lock away an innocent person if the evidence is just not good enough. Chances are high the guilty one will commit another crime and finally get caught for good.

The first time I heard about this situation was in the margins of a math textbook years ago as an example for fractions and how they can apply, I think. I also remember the last sentence saying that the case was thrown out because the probabilities were not enough. Wouldn't expect a much of a history lesson from a math textbook but this video filled in those gaps.

The problem is that in a typical courtroom the only person who understands maths is an expert witness that has been brought in to fabricate some result. Unless the person on trial happens to be a mathematician or engineer.

The basic logic was “The crime was committed by a pair matching this set of descriptors. There is a 1-in-12,000,000 chance that any two people would fit this description. Therefore, in a city of ~7.5 million, it is statistically impossible for there to be another couple matching these descriptors. By process of elimination, it must have been these two!” If you don’t know any of the case details, the source of the odds, or how probability and statistics actually work, it sounds fairly reasonable.
