Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  A subpoena duces tecum

  Why it's wrong here

  A subpoena duces tecum is a court order compelling a person or entity to produce documents, records, or other tangible items, but it does not authorize law enforcement to physically seize a computer. In criminal investigations, seizure of a computer without a warrant is only permitted under exceptions such as consent or exigent circumstances; a subpoena alone cannot justify a search or seizure, and noncompliance is typically addressed through contempt proceedings rather than immediate confiscation. Thus, it is not a valid lawful basis for seizing a computer under the Fourth Amendment.

• ✗

  No legal authorization is needed if the computer is in plain view

  Why it's wrong here

  The plain view doctrine allows officers to seize evidence that is immediately apparent as incriminating and is observed from a lawful vantage point, but it does not automatically permit the seizure of a computer or the search of its digital contents. For the exception to apply, the incriminating nature of the object itself must be 'immediately apparent,' and a computer is a closed container of data whose content cannot be inspected without further intrusion. Even if a computer is in plain view during a lawful search, accessing its files requires a separate warrant or a recognized exception, so the claim that no legal authorization is needed is overbroad and incorrect.

• ✓

  Consent of the owner, a warrant, or exigent circumstances

  Why this is correct

  A computer may be lawfully seized under the Fourth Amendment based on (1) a warrant issued by a judge upon probable cause and particularly describing the things to be seized; (2) voluntary and intelligent consent given by the owner or a person with apparent authority, which can be limited in scope; or (3) exigent circumstances, such as imminent destruction of evidence or a threat to safety, that justify immediate action before obtaining a warrant. These are well-established exceptions routinely applied in digital forensics, allowing officers to secure a device while awaiting a warrant or to accept a user's consent to search and seize it. Therefore, this option correctly enumerates the primary situations in which computer seizure is lawful.

• ✗

  Only a warrant issued by a judge

  Why it's wrong here

  Requiring a warrant as the only means to seize a computer ignores the Supreme Court's repeated recognition that the Fourth Amendment's warrant clause is not absolute and that certain exceptions have long been part of criminal procedure. Officers may lawfully seize a computer with the owner's voluntary consent, or when exigent circumstances such as the imminent destruction or tampering of digital evidence necessitate immediate action to preserve the device. In the context of computer evidence, courts have consistently applied these exceptions, meaning a judge-issued warrant is not the exclusive route to lawful seizure. Consequently, the statement that only a warrant can justify seizure is overbroad and incorrect.
