ú  Applies to bank documents. There is no REP in negotiable instruments to be used in commercial transactions, documents containing only information voluntarily conveyed and exposed to bank employees in the ordinary course of business. (Miller)
§  Binary drug test

ú  No REP where a private party has previously opened an effect, which remains unsealed, and government agents have been invited to examine its contents. (Jacobsen)

and articulable facts and circumstances before the officer are such as to warrant a man of reasonable prudence and caution to believe that an offense has been committed or is being committed based on totality of the circumstances.
§  Examples
ú  When a citizen has recently and repeatedly given substantial ground for believing that he is engaged in criminal acts, then is stopped by an officer in that region who knows that at the time of the stop, and the circumstances under which the stop is made do not indicate that the suspect is going about legitimate affairs, then there is PC. (Brinegar)
ú  If an informant is known to be reliable and there is corroboration of an informant’s information there is PC. (Draper)
ú  Information given to an officer coming from an informant whose information had always been found accurate and reliable can establish PC. (Draper)
ú  The totality of the circumstances analysis should be used to determine PC, and basis of an informant’s knowledge and veracity of an informant are factors to be considered. (Gates)
