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.
Deleting a text, photo, email or file does not always destroy it. Copies, backups, cloud systems, recipients and forensic recovery can allow supposedly deleted evidence to reappear months or years later.
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.
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.
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.
Modern cars can record location, speed, braking, diagnostics and driving behavior. As vehicles become computers on wheels, a growing legal fight is developing over who can collect, use, share and control that data.
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.
Screenshots of texts, social media posts and websites appear in court every day. But a screenshot does not prove itself. Courts still have to determine what it shows, where it came from and whether it is authentic.
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.
Social media posts can survive for years through screenshots, account records and other copies. When a lawsuit, criminal case or other dispute begins, an old post can become evidence with consequences its author never anticipated.
Some cases turn on evidence that was there from the beginning but seemed unimportant at first. A receipt, photograph, timestamp or forgotten record can take on an entirely different meaning once a case reaches trial.
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.
