Police received an anonymous telephone tip that respondent White
would be leaving a particular apartment at a particular time in a
particular vehicle, that she would be going to a particular motel,
and that she would be in possession of cocaine. They immediately
proceeded to the apartment building, saw a vehicle matching the
caller's description, observed White as she left the building and
entered the vehicle, and followed her along the most direct route
to the motel, stopping her vehicle just short of the motel. A
consensual search of the vehicle revealed marijuana and, after
White was arrested, cocaine was found in her purse. The Court of
Criminal Appeals of Alabama reversed her conviction on possession
charges, holding that the trial court should have suppressed the
marijuana and cocaine because the officers did not have the
reasonable suspicion necessary under
Terry v. Ohio,
392 U. S. 1, to
justify the investigatory stop of the vehicle.
Held: The anonymous tip, as corroborated by independent
police work, exhibited sufficient indicia of reliability to provide
reasonable suspicion to make the investigatory stop. Pp.
496 U. S.
328-332.
(a) Under
Adams v. Williams, 407 U.
S. 143,
407 U. S. 147,
an informant's tip may carry sufficient "indicia of reliability" to
justify a
Terry stop even though it may be insufficient to
support an arrest or search warrant. Moreover,
Illinois v.
Gates, 462 U. S. 213,
462 U. S. 230,
adopted a "totality of the circumstances" approach to determining
whether an informant's tip establishes probable cause, whereby the
informant's veracity, reliability, and basis of knowledge are
highly relevant. These factors are also relevant in the reasonable
suspicion context, although allowance must be made in applying them
for the lesser showing required to meet that standard. Pp.
496 U. S.
328-329.
(b) Standing alone, the tip here is completely lacking in the
necessary indicia of reliability, since it provides virtually
nothing from which one might conclude that the caller is honest or
his information reliable, and gives no indication of the basis for
his predictions regarding White's criminal activities.
See
Gates, supra, at
462 U. S. 227.
However, although it is a close question, the totality of the
circumstances demonstrates that significant aspects of the
informant's story were sufficiently corroborated by the police to
furnish reasonable suspicion. Although not every detail
Page 496 U. S. 326
mentioned by the tipster was verified --
e.g., the name
of the woman leaving the apartment building or the precise
apartment from which she left -- the officers did corroborate that
a woman left the building and got into the described vehicle. Given
the facts that they proceeded to the building immediately after the
call, and that White emerged not too long thereafter, it also
appears that her departure was within the timeframe predicted by
the caller. Moreover, since her four-mile route was the most direct
way to the motel, but nevertheless involved several turns, the
caller's prediction of her destination was significantly
corroborated, even though she was stopped before she reached the
motel. Furthermore, the fact that the caller was able to predict
her future behavior demonstrates a special familiarity with her
affairs. Thus there was reason to believe that the caller was
honest and well informed, and to impart some degree of reliability
to his allegation that White was engaged in criminal activity.

Justice WHITE delivered the opinion of the Court.
Based on an anonymous telephone tip, police stopped respondent's
vehicle. A consensual search of the car revealed drugs. The issue
is whether the tip, as corroborated by independent
Page 496 U. S. 327
police work, exhibited sufficient indicia of reliability to
provide reasonable suspicion to make the investigatory stop. We
hold that it did.
On April 22, 1987, at approximately 3 p.m., Corporal B.H. Davis
of the Montgomery Police Department received a telephone call from
an anonymous person stating that Vanessa White would be leaving
235-C Lynwood Terrace Apartments at a particular time in a brown
Plymouth station wagon with the right taillight lens broken, that
she would be going to Dobey's Motel, and that she would be in
possession of about an ounce of cocaine inside a brown attache
case. Corporal Davis and his partner, Corporal P. A. Reynolds,
proceeded to the Lynwood Terrace Apartments. The officers saw a
brown Plymouth station wagon with a broken right taillight in the
parking lot in front of the 235 building. The officers observed
respondent leave the 235 building, carrying nothing in her hands,
and enter the station wagon. They followed the vehicle as it drove
the most direct route to Dobey's Motel. When the vehicle reached
the Mobile Highway, on which Dobey's Motel is located, Corporal
Reynolds requested a patrol unit to stop the vehicle. The vehicle
was stopped at approximately 4:18 p.m., just short of Dobey's
Motel. Corporal Davis asked respondent to step to the rear of her
car, where he informed her that she had been stopped because she
was suspected of carrying cocaine in the vehicle. He asked if they
could look for cocaine, and respondent said they could look. The
officers found a locked brown attache case in the car and, upon
request, respondent provided the combination to the lock. The
officers found marijuana in the attache case, and placed respondent
under arrest. During processing at the station, the officers found
three milligrams of cocaine in respondent's purse.
Respondent was charged in Montgomery County court with
possession of marijuana and possession of cocaine. The trial court
denied respondent's motion to suppress, and she pleaded guilty to
the charges, reserving the right to appeal
Page 496 U. S. 328
the denial of her suppression motion. The Court of Criminal
Appeals of Alabama held that the officers did not have the
reasonable suspicion necessary under
Terry v. Ohio,
392 U. S. 1 (1968),
to justify the investigatory stop of respondent's car, and that the
marijuana and cocaine were fruits of respondent's unconstitutional
detention. The court concluded that respondent's motion to dismiss
should have been granted, and reversed her conviction.
550 So. 2d 1074 (1989). The Supreme Court of Alabama denied the
State's petition for writ of certiorari, two justices dissenting.
550 So.
2d 1081 (1989). Because of differing views in the state and
federal courts over whether an anonymous tip may furnish reasonable
suspicion for a stop, we granted the State's petition for
certiorari, 493 U.S. 1042 (1990). We now reverse.
Adams v. Williams, 407 U. S. 143
(1972), sustained a
Terry stop and frisk undertaken on the
basis of a tip given in person by a known informant who had
provided information in the past. We concluded that, while the
unverified tip may have been insufficient to support an arrest or
search warrant, the information carried sufficient "indicia of
reliability" to justify a forcible stop. 407 U.S. at
407 U. S. 147.
We did not address the issue of anonymous tips in
Adams
except to say that "[t]his is a stronger case than obtains in the
case of an anonymous telephone tip,"
id. at
407 U. S.
146.
Illinois v. Gates, 462 U. S. 213
(1983), dealt with an anonymous tip in the probable cause context.
The Court there abandoned the "two-pronged test" of
Aguilar v.
Texas, 378 U. S. 108
(1964), and
Spinelli v. United States, 393 U.
S. 410 (1969), in favor of a "totality of the
circumstances" approach to determining whether an informant's tip
establishes probable cause.
Gates made clear, however,
that those factors that had been considered critical under
Aguilar and
Spinelli -- an informant's
"veracity," "reliability," and "basis of knowledge" -- remain
"highly relevant in determining the value of his report." 462 U.S.
at
462 U. S. 230.
These factors are also relevant in the reasonable suspicion
context, although allowance
Page 496 U. S. 329
must be made in applying them for the lesser showing required to
meet that standard.
The opinion in
Gates recognized that an anonymous tip
alone seldom demonstrates the informant's basis of knowledge or
veracity, inasmuch as ordinary citizens generally do not provide
extensive recitations of the basis of their everyday observations,
and given that the veracity of persons supplying anonymous tips is
"by hypothesis largely unknown and unknowable,"
Id. at
462 U. S. 237.
This is not to say that an anonymous caller could never provide the
reasonable suspicion necessary for a
Terry stop. But the
tip in
Gates was not an exception to the general rule, and
the anonymous tip in this case is like the one in
Gates:
"[it] provides virtually nothing from which one might conclude
that [the caller] is either honest or his information reliable;
likewise, the [tip] gives absolutely no indication of the basis for
the [caller's] predictions regarding [Vanessa White's] criminal
activities."
462 U.S. at
462 U. S. 227.
By requiring "[s]omething more," as
Gates did,
ibid., we merely apply what we said in
Adams:
"Some tips, completely lacking in indicia of reliability, would
either warrant no police response or require further investigation
before a forcible stop of a suspect would be authorized,"
407 U.S. at
470 U. S. 147.
Simply put, a tip such as this one, standing alone, would not
"
warrant a man of reasonable caution in the belief' that [a
stop] was appropriate." Terry, supra, 392 U.S. at
392 U. S. 22,
quoting Carroll v. United States, 267 U.
S. 132, 267 U. S. 162
(1925).
As there was in
Gates, however, in this case there is
more than the tip itself. The tip was not as detailed, and the
corroboration was not as complete, as in
Gates, but the
required degree of suspicion was likewise not as high. We discussed
the difference in the two standards last Term in
United States
v. Sokolow, 490 U. S. 1,
490 U. S. 7
(1989):
"The officer [making a
Terry stop] . . . must be able
to articulate something more than an "inchoate and unparticularized
suspicion or
hunch.'" [Terry, 392 U.S.] at
392 U. S. 27 .
The Fourth Amendment requires "some minimal
Page 496 U. S. 330
level of objective justification" for making the stop.
INS
v. Delgado, 466 U. S. 210
(1984). That level of suspicion is considerably less than proof of
wrongdoing by a preponderance of the evidence. We have held that
probable cause means "a fair probability that contraband or
evidence of a crime will be found," [
Gates, 462 U.S. at
462 U. S.
238], and the level of suspicion required for a
Terry stop is obviously less demanding than for probable
cause."
Reasonable suspicion is a less demanding standard than probable
cause not only in the sense that reasonable suspicion can be
established with information that is different in quantity or
content than that required to establish probable cause, but also in
the sense that reasonable suspicion can arise from information that
is less reliable than that required to show probable cause.
Adams v. Williams, supra, demonstrates as much. We there
assumed that the unverified tip from the known informant might not
have been reliable enough to establish probable cause, but
nevertheless found it sufficiently reliable to justify a
Terry stop. 407 U.S. at
407 U. S. 147.
Reasonable suspicion, like probable cause, is dependent upon both
the content of information possessed by police and its degree of
reliability. Both factors -- quantity and quality -- are considered
in the "totality of the circumstances -- the whole picture,"
United States v. Cortez, 449 U. S. 411,
449 U. S. 417
(1981), that must be taken into account when evaluating whether
there is reasonable suspicion. Thus, if a tip has a relatively low
degree of reliability, more information will be required to
establish the requisite quantum of suspicion than would be required
if the tip were more reliable. The
Gates Court applied its
totality of the circumstances approach in this manner, taking into
account the facts known to the officers from personal observation,
and giving the anonymous tip the weight it deserved in light of its
indicia of reliability as established through independent police
work. The same approach applies in the reasonable suspicion
context, the only difference
Page 496 U. S. 331
being the level of suspicion that must be established. Contrary
to the court below, we conclude that when the officers stopped
respondent, the anonymous tip had been sufficiently corroborated to
furnish reasonable suspicion that respondent was engaged in
criminal activity, and that the investigative stop therefore did
not violate the Fourth Amendment.
It is true that not every detail mentioned by the tipster was
verified, such as the name of the woman leaving the building or the
precise apartment from which she left; but the officers did
corroborate that a woman left the 235 building and got into the
particular vehicle that was described by the caller. With respect
to the time of departure predicted by the informant, Corporal Davis
testified that the caller gave a particular time when the woman
would be leaving, App. 5, but he did not state what that time was.
He did testify that, after the call, he and his partner proceeded
to the Lynwood Terrace Apartments to put the 235 building under
surveillance,
id. at 5-6. Given the facts that the
officers proceeded to the indicated address immediately after the
call, and that respondent emerged not too long thereafter, it
appears from the record before us that respondent's departure from
the building was within the timeframe predicted by the caller. As
for the caller's prediction of respondent's destination, it is true
that the officers stopped her just short of Dobey's Motel and did
not know whether she would have pulled in or continued on past it.
But, given that the four-mile route driven by respondent was the
most direct route possible to Dobey's Motel, 550 So. 2d at 1075,
Tr. of Oral Arg. 24, but nevertheless involved several turns, App.
7, Tr. of Oral Arg. 24, we think respondent's destination was
significantly corroborated.
The Court's opinion in
Gates gave credit to the
proposition that, because an informant is shown to be right about
some things, he is probably right about other facts that he has
alleged, including the claim that the object of the tip is engaged
in criminal activity. 462 U.S. at
462 U. S. 244.
Thus, it is not
Page 496 U. S. 332
unreasonable to conclude in this case that the independent
corroboration by the police of significant aspects of the
informer's predictions imparted some degree of reliability to the
other allegations made by the caller.
We think it also important that, as in
Gates,
"the anonymous [tip] contained a range of details relating not
just to easily obtained facts and conditions existing at the time
of the tip, but to future actions of third parties ordinarily not
easily predicted."
Gates, 462 U.S. at
462 U. S. 245.
The fact that the officers found a car precisely matching the
caller's description in front of the 235 building is an example of
the former. Anyone could have "predicted" that fact, because it was
a condition presumably existing at the time of the call. What was
important was the caller's ability to predict respondent's
future behavior, because it demonstrated inside
information -- a special familiarity with respondent's affairs. The
general public would have had no way of knowing that respondent
would shortly leave the building, get in the described car, and
drive the most direct route to Dobey's Motel. Because only a small
number of people are generally privy to an individual's itinerary,
it is reasonable for police to believe that a person with access to
such information is likely to also have access to reliable
information about that individual's illegal activities.
See
Gates, supra, at
462 U. S. 245.
When significant aspects of the caller's predictions were verified,
there was reason to believe not only that the caller was honest,
but also that he was well informed, at least well enough to justify
the stop.
Although it is a close case, we conclude that, under the
totality of the circumstances, the anonymous tip, as corroborated,
exhibited sufficient indicia of reliability to justify the
investigatory stop of respondent's car. We therefore reverse the
judgment of the Court of Criminal Appeals of Alabama, and remand
for further proceedings not inconsistent with this opinion.
So ordered.
Page 496 U. S. 333
Justice STEVENS, with whom Justice BRENNAN and Justice MARSHALL
join, dissenting.
Millions of people leave their apartments at about the same time
every day, carrying an attache case and heading for a destination
known to their neighbors. Usually, however, the neighbors do not
know what the briefcase contains. An anonymous neighbor's
prediction about somebody's time of departure and probable
destination is anything but a reliable basis for assuming that the
commuter is in possession of an illegal substance -- particularly
when the person is not even carrying the attache case described by
the tipster.
The record in this case does not tell us how often respondent
drove from the Lynwood Terrace Apartments to Dobey's Motel; for all
we know, she may have been a room clerk or telephone operator
working the evening shift. It does not tell us whether Officer
Davis made any effort to ascertain the informer's identity, his
reason for calling, or the basis of his prediction about
respondent's destination. Indeed, for all that this record tells
us, the tipster may well have been another police officer who had a
"hunch" that respondent might have cocaine in her attache case.
Anybody with enough knowledge about a given person to make her
the target of a prank, or to harbor a grudge against her, will
certainly be able to formulate a tip about her like the one
predicting Vanessa White's excursion. In addition, under the
Court's holding, every citizen is subject to being seized and
questioned by any officer who is prepared to testify that the
warrantless stop was based on an anonymous tip predicting whatever
conduct the officer just observed. Fortunately, the vast majority
of those in our law enforcement community would not adopt such a
practice. But the Fourth Amendment was intended to protect the
citizen from the over-zealous and unscrupulous officer, as well as
from those who are conscientious and truthful. This decision makes
a mockery of that protection.
I respectfully dissent.
