Is it true that any digital evidence obtained without a search warrant is inadmissible in court?

The statement is false because not all digital evidence obtained without a search warrant is automatically inadmissible in court. While the Fourth Amendment of the U.S. Constitution protects against unreasonable searches and seizures and typically requires a warrant for police to search a person's property or seize their belongings, there are several exceptions to this rule.

For instance, evidence may be admissible if it falls under the "exigent circumstances" exception, where law enforcement has a reasonable belief that evidence may be destroyed or that there is an imminent threat to public safety. Additionally, if the individual gives consent to search without a warrant, that evidence may also be admissible. Other exceptions include situations involving specialty areas such as plain view doctrine, where evidence is observed in plain sight during a lawful presence, or during the arrest of a suspect.

Therefore, while a warrant is preferred for collecting evidence, it is not the only means by which digital evidence can be legally obtained and used in court.
