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.
Doorbell cameras, store surveillance systems and home security cameras record far more than crimes against their owners. When something happens nearby, privately recorded video can become important evidence in a police investigation.
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?
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 collision that initially looks minor can become a major lawsuit months later. Medical complications, disputed fault, hidden injuries, insurance limits and unexpected evidence can transform an ordinary accident case.
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.
AI can now create convincing photographs, recordings and voices depicting events that never happened. Deepfakes are forcing courts to reconsider how digital evidence can be authenticated and trusted.
Some cases have no eyewitness, confession or video of the critical event. Instead, lawyers build the story from timing, records, behavior, physical evidence and dozens of facts that may look insignificant until they are put together.
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 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.
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.
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.
