A forgotten recording, newly found document, DNA result or unexpected witness can surface after a verdict and challenge what everyone thought was settled. But new evidence does not automatically reopen a closed case.
A doorbell camera installed to protect one home can capture a crash, theft, missing person or crime involving complete strangers. That ordinary recording can later become important evidence in someone else’s case.
A locked phone can contain years of private information. Whether the government can force someone to unlock it may depend on how it is locked, what investigators already know and which court is deciding the issue.
A witness gives one account immediately after an event and another months later. Changed stories can reshape a case—but the reason for the change may matter as much as the inconsistency itself.
DNA can identify more than the person who provided it. Genetic genealogy can use biological relationships to generate investigative leads, raising lasting questions about crime solving, family privacy and genetic data.
Hours of surveillance footage can matter less than a few decisive seconds. A brief recording can contradict a witness, establish a timeline, reveal what happened before an encounter, or completely change how a case is understood.
Facial recognition is turning the human face into a searchable identifier used by phones, airports, businesses and law enforcement, raising lasting questions about privacy, accuracy and identity.
Modern investigations can use location data to identify devices near a crime scene, potentially drawing innocent bystanders into an investigation simply because their phones were nearby.
A mistaken identification, shared name, bad database entry or flawed investigation can put an innocent person in handcuffs. What happens when police arrest the wrong person—and the mistake is not discovered immediately?
A fence, tree, driveway, noise complaint or property line can turn two neighbors into courtroom opponents. Neighbor disputes show how small conflicts become expensive lawsuits—and why the original disagreement is often only the beginning.
A confession can seem like the strongest evidence imaginable. Yet documented wrongful convictions show that innocent people sometimes confess—and understanding why can completely change how a case is viewed.
Police can search many things after making a lawful arrest, but a smartphone is different. Here is why the Supreme Court generally requires a warrant before officers search the digital contents of an arrested person's phone.
