The Fourth Amendment in the Digital Era: Applying the Private Search Doctrine to Flash Drives and Other Electronic Media Storage Devices

There is currently a circuit court split as to how the private search doctrine, a judicially-created framework under the Fourth Amendment, applies in the context of electronic media storage devices, such as flash drives—either via a “narrow approach” or a “broad approach.” Without further guidance from the Supreme Court, police officers in some jurisdictions are effectively given authority to end-run around the Fourth Amendment. In this Contribution, William Walant (‘22) argues that the Supreme Court should adopt the “narrow approach,” which focuses on the unique nature of digital media devices. This focus is embraced in Riley v. California and is consistent with the private search doctrine’s underlying principles. However, unlike as has been suggested by some recent scholarship, the private search doctrine need not be altered to fit electronic media storage devices, and the narrow approach does not create insurmountable and undesirable consequences. Instead, by adopting a narrow approach, the private search doctrine can be preserved while reaching a positive outcome for society: an officer, absent exigent circumstances or other exceptions, will be incentivized to obtain a warrant to examine the contents of an electronic device handed over by a private party.

Fear of Needles or Guilty Conscience? The Fourth Amendment and the Use of BAC Test Refusal Evidence in DUI Prosecutions

When a motorist is arrested on suspicion of intoxicated driving, the government cannot compel him to submit to a blood draw without a warrant or warrant exception, nor can it make his refusal to submit to a blood draw a crime. But can the government use the refusal as evidence of guilt in a subsequent DUI prosecution on the basis of an implied consent statute? In this Contribution, Max Baumbach (’21) argues that the Fourth Amendment prohibits the use of blood test refusal evidence in a DUI prosecution where the test itself would have been unlawful to conduct in the first instance.
