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.
An ordinary photograph can preserve evidence nobody noticed when it was taken. Reflections, shadows, clocks, clothing, background objects and tiny details can later establish where someone was, when something happened, or whether a story is possible.
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.
Photos, email, social media, cloud files and online accounts can survive long after their owner dies. The law increasingly has to decide who may access, preserve or control a person's digital life.
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 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.
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.
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.
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 witness can look directly at a defendant and sincerely say, “That's the person I saw,” yet still be mistaken. Decades of wrongful-conviction cases have changed what courts know about eyewitness memory and certainty.
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.
