Requirements for establishing probable cause through reliance on information received from an informant has divided the Court in several cases. Although involving a warrantless arrest, Draper v. United States 103 may be said to have begun the line of cases.
A previously reliable, named informant reported to an officer that the defendant would arrive with narcotics on a particular train, and described the clothes he would be wearing and the bag he would be carrying; the informant, however, gave no basis for his information. FBI agents met the train, observed that the defendant fully answered the description, and arrested him. The Court held that the corroboration of part of the informer's tip established probable cause to support the arrest.
A case involving a search warrant, Jones v. United States, 104 apparently utilized a test of considering the affidavit as a whole to see whether the tip plus the corroborating information provided a substantial basis for finding probable cause, but the affidavit also set forth the reliability of the informer and sufficient detail to indicate that the tip was based on the informant's personal observation. Aguilar v. Texas 105 held insufficient an affidavit which merely asserted that the police had ''reliable information from a credible person'' that narcotics were in a certain place, and held that when the affiant relies on an informant's tip he must present two types of evidence to the magistrate. First, the affidavit must indicate the informant's basis of knowledge--the circumstances from which the informant concluded that evidence was present or that crimes had been committed--and, second, the affiant must present information which would permit the magistrate to decide whether or not the informant was trustworthy. Then, in Spinelli v. United States, 106 the Court applied Aguilar in a situation in which the affidavit contained both an informant's tip and police information of a corroborating nature.
