Federal Judicial Treatment of Informers - Admissibility,
Credibility and Constitutional Considerations
The federal1 government's use of informers, paid and unpaid, is undeniably widespread, valuable in criminal law enforcement, and constitutionally suspect However, as vital as their services may be to law enforcement officials, informers would be little used were it not for the
judicially approved rule that "artifice and stratagem may be employed to
catch those engaged in criminal enterprises. ' This Note examines the
judicial treatment of informers' testimony, its admissibility, and the basis
for constitutional attack, noting that all of these aspects" are inseparably
related.
An informer is one who voluntarily reports law violations or suspected
violations to an agent of the government.5 Although the informer is often
a public-spirited citizen,' he may instead be one who has participated in
a crime and subsequently turned against his partners; a "plant" employed
by law enforcement agencies to participate in the commission of a crime;'
' Since there is no appreciable difference
between state and federal treatment of informers,
this Note primarily focuses on informers at the federal court level, with an incidental consideration
of them at the state level. Similarly, focus is on trial considerations; the pre-trial use of informers
to prompt confessions by suspects is not treated. Entrapment, a closely related but distinguishable
field, is necessarily omitted.
a See Donnelly, Judicial Control of Informants, Spies, Stool Pigeons, and Agent Provocateurs,
60 YALE L.J. 1091 (1951). Although the informers themselves have generally elicited the concurrent
reactions of contempt and aversion, police forces the world over see wisdom in the extensive use
of such persons, for the role they play in criminal law is of great magnitude.

' Another aspect is the "informer's privilege," not treated separately, but definitely to be kept
in mind, since it is probable that few persons would be willing to impart information to the police
without absolute promise of secrecy. The privilege, assertable by either the government or the
court, provides that in the absence of statute, disclosure of the informer's identity ordinarily will
not be compelled. Roviaro v. United States, 353 U.S. 53 (1957); Mitrovich v. United States, 15
F.2d 163 (9th Cir. 1926); People v. Lawrence, 149 Cal. App. 2d 435, 308 P.2d 821 (1957). The
privilege forbids only nonessential disclosure; disclosure may always be compelled in cases where
identity of the informer appears essential to the defense. Scher v. United States, 305 U.S. 251
(1938); Portomene v. United States, 221 F.2d 582 (5th Cir. 1955). An undecided related issue
is whether to permit nondisclosure of the contents of the informer's report. For nondisclosure,

to a legal proceeding); Pollock v. The Laura, 5 F. 133, 141 (S.D.N.Y. 1880) (a person who lodges

procures an action against another, whom he suspects of the violation of some penal statute).
A variety of motives are ascribed as to what would prompt one to be an informer: promises of
immunity or leniency, revenge, fear, money, jealousy, friendship with members of the police force,
or even a desire to seek out criminals for society's sake. See Donnelly, supra note 2, at 1092.

This type is considered a "feigned accomplice" and thus is not subject to traditional accomplice
rules if he merely feigns complicity in the commission of crimes for the purpose of securing evidence
(and if his conduct falls short of entrapment), since he will be lacking in the requisite criminal
intent. Smith v. United States, 17 F.2d 723 (8th Cir.), cert. denied, 274 U.S. 762 (1927); Lett
v. United States, 15 F.2d 690 (8th Cir. 1926); Finley v. State, 84 Okla. Crim. 309, 181 P.2d
849 (1947). This same reasoning applies to paid informers. Smith v. United States, supra. The

and one urged by the government to uncover evidence of crime.8 As will
be seen, these latter sources of information are most subjected to court
attack on constitutional grounds. And their proffered testimony often
raises issues of credibility and admissibility.
I. INFORMERS'
TESTIMONY AND CREDIBILITY
The evidentiary field presents recurring problems of admissibility and
credibility. The general rule is that an informer's testimony is considered
competent and is to be weighed like the testimony of any other witness.9
When so weighed, it may be sufficient to sustain a conviction, ° even
though the testimony is not corroborated." As to admissibility of the informer's testimony, the common law rule was that evidence which met the
tests of relevancy and verity was admissible." The fact that it was illegally
obtained was immaterial because the courts would not inquire into the
circumstances of the acquisition of material evidence." Today admissibility
is more restricted; evidence obtained by illegal means is no longer constitutionally admissible. " Otherwise, the standards for admissibility are
still quite liberal. Eavesdropping, for example, is still condoned. Generally,
