Two cameras can record the same event and make it look completely different. Angle, timing, sound, missing seconds and perspective can turn video evidence into the beginning of a courtroom dispute rather than the end of one.
Modern cars can generate location, navigation and driving data long after a trip ends. When police investigate a crime, information created by the vehicle itself can become evidence.
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.
Facial recognition and other automated systems can give police powerful investigative leads. When the technology makes a mistake, however, an innocent person can suddenly become the focus of an investigation.
A few recorded words can transform a lawsuit or criminal case. Phone calls, voicemails, body cameras and other recordings can expose contradictions, preserve admissions and reveal what witnesses said before they knew a courtroom was coming.
A receipt can establish where money went, when a purchase happened and whether a story fits the records. But sometimes the most important evidence is the receipt that should exist—and doesn't.
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.
AI systems increasingly help make decisions about employment, credit, insurance, housing and other opportunities. When an automated decision causes harm, the law still has to determine who is responsible.
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.
Witnesses can disagree about what happened, but timestamps often tell a different story. Phone records, receipts, cameras, access logs and other records can turn a confusing case into a minute-by-minute reconstruction.
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.
