Bryаn Roberts was convicted after a jury trial of conspiracy to operate an illegal gambling business, 18 U.S.C. § 371, operating such a business, 18 U.S.C. § 1955, and failure to file a special tax return with the Internal Revenue Service before receiving wagers on sporting events, 26 U.S.C. § 7203. He seeks reversal on the grounds thаt the district judge erroneously refused to suppress evidence seized at his apartment and improperly admitted evidence of a prior conviction. Because we find both contentions to be without merit, we affirm.
I.
Deputy sheriffs arrived at Bryan Roberts’s El Paso, Texas apartment to execute a search warrant issued by a state judge. The warrant authorized search for a stolen television set. After Roberts answered the officers’ knock at the door of his apartment, they entered the apartment where they discovered the stolen television set and took Robеrts into custody.
In the living-dining area of the apartment where they found the television set, the deputies observed two tables upon which telephones, calculators and papers were arranged. After Mr. Roberts was secured, one of the deputies glanced at the tables and notiсed a football score sheet next to one of the telephones. This telephone receiver was off the hook; the offi-' cer picked it up and said “hello.” The party on the line replied, “give me Southern California minus 4.” Convinced that they had discovered an illegal gambling operation, the deputies contacted the F.B.I. Federal agents arrived and they joined the local police in seizing evidence of the operation from the tables and from open closets in the living-dining area of the apartment. Roberts’s motion to suppress the evidencе was denied and much of it was introduced at trial.
It is not disputed that all the evidence sought to be suppressed was in the plain view of the officers as they moved about the apartment while executing the state-issued search warrant. Nevertheless, Roberts contends that, because the оfficers had to read the papers on the tables before they could determine that he was running a gambling operation, the discovery that the materials were evidence of a crime was made by a search beyond the purview of the “plain view” doctrine enunciated in
Coolidge v. New Hampshire,
We have held that the seizure of material cannot be justified by the plain view theory when the incriminating or evidentiary character of the material becomes known only after close inspection.
See United States v. Robinson,
Here, however, the incriminating character of the items seized was apparent to the police officers by casual inspection. A mere glance at the papers on the table revealed a football scoresheet. The appearance of the apartment suggested a business operation. These two facts were enough to give the deputies reason to believe that they had unwittingly discovered a bookmaking operation. Once they were alerted to the existence of the operation, they had probable cause to believe that the items were evidence and, because they were legitimately in a рosition to seize the evidence, requiring them to obtain a warrant would have been a “needless inconvenience” unrelated to protection of any fourth amendment interests.
See Coolidge,
Police officers are not required to ignore the significance of items in plain view even when the full imрort of the objects cannot be positively ascertained without some examination. Thus, we have held the seizure of address books in plain view valid even though the officer first paged through them because the officer had “recognized that the address books might be of significance bеfore he leafed through them.”
United States v. Diecidue,
Contrary to defendant’s assertions, the decision to communicate with the F.B.I. and await the arrival of federal officers before seizing the evidence does not affect the validity of the seizure. The state officers seized and took custody of the evidence as they would have done regardless of the presence of federal officers^ There was no attempt by the state or federal officers to utilize the plain view doctrine to avoid the requirement of obtaining a warrant.
Cf. United States v. Sanchez,
II.
During the triаl, the government informed defense counsel that it intended, as part of its case in chief, to introduce the defendant’s prior conviction of a gambling offense. Defense counsel argued that this evidence should not be admitted unless the defendant raised the issue of intent in his defense. The trial сourt ruled that Roberts’s plea of not guilty itself raised the *382 issue of intent, thus making this particular prior conviction relevant.
Rule 404(b) of the Federal Rules of Evidence permits the admission of extrinsic offense evidence to prove intent as well as certain other issues. Whether a not guilty plea of itself sufficiently raises the issue of intent to make extrinsic offense evidence admissible in the government’s case in chief is a question we have reserved in our previous decisions.
See United States v. McMahon,
We have established a two-prong test for determining whether extrinsic offense evidence is admissible to prove intent.
See United States v. Beechum,
Charges of conspiracy involve considerations not present in other criminal prosecutions. “[T]he offense of conspiracy requires an element of intent or knowledge which is often difficult to prove.”
United States v.
*383
McMahon,
Unequivocal evidence that a defendant committed a substantive offense may justify the inferenсe that he intended to do so, but it does not plainly support the conclusion that he agreed and planned with others to commit the crime. Evidence of a defendant’s association and dealings with a group of conspirators, even when he knows they intend to commit a crime, does nоt alone show that he himself had the requisite intent to join the conspiracy.
See United States v. Grassi,
Roberts’s defense counsel did not, however, affirmatively remove the issue of intent from the case when he raised his motion to exclude the extrinsic offense evidence. He indicatеd only that he would not actively contest the issue. That alone did not reduce the burden on the prosecution to establish intent, as an element of the offense, beyond reasonable doubt. Indeed, in defense counsel’s argument to the jury he took the position that the defendant had not jоined the conspiracy, but was merely an employee of the conspirators with no independent interest in the bookmaking operation.
Because of the unique nature of conspiracy charges, we cannot apply to them the policy suggested in
Beechum
of uniformly excluding extrinsic оffense evidence when the defendant does not actively contest intent.
See
In this case we cannot say that the probative value of the evidence was “substantially outweighed by the danger of unfair prejudice” to the defendant. Fed.R.Evid. 403;
Beechum,
For these reasons, the judgment of conviction is AFFIRMED.
Notes
. Other courts, as we did prior to
Beechum,
analyze the rule 404(b) issue somewhat differently when intent is uncontested, focusing on whether'the extrinsic offense evidence can be considered relevant if intent is not contested.
See
Fed.R.Evid. 401 (evidence is relevant when it has “аny tendency to make the existence of any fact
that is of consequence
to the determination of the action” more probable than it would be without the evidence.
Id.
(emphasis supplied)).
See e. g., United States v. Powell, 587
F.2d 443 (9th Cir. 1978) (denial of participation in acts that constitute the crime does not raise intent issue);
United States v. Silva,
In
Beechum,
however, we impliedly rejected that approach, noting that “[a]lthough it would seem that the extrinsic offense would be irrelevant if the issue of intent were not cоntested, the rules apparently deem evidence that has probative force with regard to an uncontested issue to be relevant.”
. If, for example, the defendant intends to take the stand and deny any participation in the acts evidencing а conspiracy, he may wish to stipulate that those acts prove intent if his participation is established to the satisfaction of the jury. Similarly, a defendant who intends to assert a defense based upon mistaken identity may make an appropriate stipulation to avoid the introduction of extrinsic offense evidence.
