Can Science Stop Crime?: Introduction (01:41)

FREE PREVIEW

This segment orients viewers to the topic of crime fighting techniques, the warrior gene, lie detection, and determining the time of death.

Keeping Teens off the Streets (02:29)

Host David Pogue questions whether nature or nurture creates violent brains; he takes boxing lessons with former gang member Eugene Jackson. Jackson's son Nikko is a top fighter; he was once a member of a Taliban gang.

Warrior Gene (02:03)

Kevin Beaver found a pattern in the profiles and criminal records. Nikko carries a controversial gene reportedly linked to violence. The Warrior Gene is a version of the MAO-A gene. Scientists engineered mice to have a dysfunctional version of the gene.

Genetic Aggression? (03:03)

Joshua Buckholtz found evidence that suggests the Warrior Gene affects vital circuitry in the brain for emotion and learning. He believes one factor is not enough to make someone violent.

Criminal Mind (02:23)

James Fallon studies the brains of violent killers. His family history includes several murderers; he and several of his immediate family members carry the Warrior Gene. Fallon reflects on why he is not violent.

Comprehensive Personality Comparison (03:55)

Scientists perform several tests, analyzing genetics, personalities, and family histories; Pogue volunteers for testing. Nelly Alia-Klein describes individuals who have intermittent explosive disorder. She uses PET scans to measure brain activity and compares the results of those with high-level and low-level aggression.

Environmental Influence (01:44)

Environments can change a person's brain structure. Genetics and environmental factors can cause an individual to be violent; a positive environment may help counteract negative risk factors.

Forensic Anthropology (02:16)

Researchers simulate a death scene to learn what happens to human bodies after death. Pogue is shocked to learn a skeleton has only been in the field three days. Time of death can be critical in cases.

Determining Time Since Death (03:27)

Medical Examiner Peter Cummings performs approximately 300 autopsies a year. He explains the role of rigor mortis in estimating a time of death.

Body Farms (02:12)

Temperature is the biggest factor in decomposition. Forensic anthropologists investigate rate, pattern, and timelines of human decomposition.

Rendering a Skeleton to Bones (03:47)

The bones of a skeleton are scattered 20 feet from where the body was placed. A camera reveals the speed and efficiency with which vultures consume a carcass; they can skew an estimation of time since death. Decaying bodies produce cadaverine and putrescine.

Lie Detection (04:56)

At the National Center for Credibility Assessment, Pogue steals cash and lies about it during a polygraph; polygraphs identify stress indicators. Experts explain sensor readings and consider polygraph reliability.

Identifying Deception (05:39)

Jennifer Vendemia and her team record images of Pogue's brain as he responds to true or false questions. Vendemia looks for the P300 brainwave; lies require a longer processing time. William Marston was an inventor of the polygraph.

Cyber Crime (03:49)

Hacker "Yoshi" Kohno tries to look at the world through the eyes of a criminal and detect weaknesses in security armor. He finds a way to see through a glass door, etched for privacy. Kohno's skills with a computer began at a young age.

Computer Hacking (02:34)

Kohno's team can hack into almost any machine that wirelessly broadcasts or receives digital information, including the iPod Sport Kit and enhanced drivers' licenses. Newer cars are equipped with computer software that could potentially be hacked.

Cyber Car Thieves (05:05)

Kohn's team successfully downloads software to a car's computer. The team takes the car to a closed track and attempts to access the braking system. Kohno's goal is to protect the security of future technologies.

Description

What's the secret to stopping crime? David Pogue gives the third degree to scientists pushing the limits of technology, not only to solve horrific murders but also to try to prevent crimes before they even happen. Pogue learns the latest techniques, from unraveling the clues embedded in a decomposing corpse, to detecting lies by peering directly into a suspect's brain, to tracking the creation of a criminal mind. And we meet a genius crime-stopper who has made some terrifying discoveries, including how easy it is for a bad guy to highjack not just your laptop but your kids' toys, medical devices, even your car.
