“ Absent additional facts for believing the informant's report, his assertion stands no better than the oath of the officer to the same effect. Indeed, if the affidavit of an officer, known by the magistrate to be honest and experienced, stating that gambling equipment is located in a certain building is unacceptable, it would be quixotic if a similar statement from an honest informant were found to furnish probable cause. ”

“ Detailed information may sometimes imply that the informant himself has observed the facts. Suppose an informant with whom an officer has had satisfactory experience states that there is gambling equipment in the living room of a specified apartment and describes in detail not only the equipment itself but also the appointments and furnishments in the apartment. ”

“ But if the officer simply avers, without more, that there is gambling paraphernalia on certain premises, the warrant should not issue, even though the belief of the officer is an honest one, as evidenced by his oath, and even though the magistrate knows him to be an experienced, intelligent officer who has been reliable in the past. ”
