THE CONSENSUS HAS BEEN THAT THERE IS NO SUBSTANTIVE DEFENSE OF ENTRAPMENT SIMILAR TO THAT EXISTING IN THE UNITED STATES. IN ADDITION, THERE IS A VALID DISTINCTION BETWEEN THE UNDERCOVER CONSTABLE WHO MERELY AFFORDS THE OPPORTUNITY TO A PERSON TO COMMIT AN OFFENCE IF HE WAS SO MINDED AND THE AGENT WHO INCITES, ENCOURAGES, BEGUILES OR SEDUCES AN OTHERWISE UNWILLING ACCUSED TO COMMIT AN OFFENCE. CONDUCT OF THE FIRST TYPE WILL BE ACCEPTED BY THE COURTS, BUT EVIDENCE OF ACTIVITY WHICH CROSSES THE LINE AND AMOUNTS TO CONDUCT OF THE SECOND TYPE WILL, IN ALL PROBABILITY, BE EXCLUDED BY THE COURT. GUIDELINES IN THIS AREA FOR UNDERCOVER POLICE OFFICERS ARE INCLUDED. (AUTHOR ABSTRACT MODIFIED)
