Courts and scholars have devoted considerable attention to the definition of probable cause and reasonable suspicion. Since the demise of the â€œmere evidence ruleâ€ in the 1960s, however, they have rarely examined how these central Fourth Amendment concepts interact with the â€œobjectâ€ of the search. That is unfortunate, because this interaction can have significant consequences. For instance, probable cause to believe that a search â€œmight lead to evidence of wrongdoingâ€ triggers a very different inquiry than probable cause to believe that a search â€œwill produce evidence of criminal activity.â€ The failure to address the constraints that should be imposed on the object of a search has particularly acute implications in the context of records searches. This article explores the ramifications of this gap in Fourth Amendment jurisprudence both generally and in connection with the NSAâ€™s metadata program, with particular attention to how the American Bar Associationâ€™s Standards on Government Access to Third Party Records, the topic of the symposium for which this article was written, resolve the relevant issues.
