Brief of the National Association of Federal Defenders and the National Association of Criminal Defense Lawyers as Amici Curiae in Support of Respondent.
Argument: The First Circuit correctly held that the search-incident-to-arrest exception does not categorically authorize warrantless cell phone searches, but that the exigent circumstances exception can apply in particular cases. Smith v. Maryland does not support a rule allowing call logs to be searched incident to arrest. Maryland v. King and Florence v. Bd. Of Chosen Freeholders do not support warrantless cell phone searches incident to arrest.
