The principal issue in this appeal is whether a theft victim’s visit to the defendant’s property to look for his stolen trailer constituted a government search and is subject to Fourth Amendment requirements. *655 Because the theft victim acted on his own and received consent to walk around the premises from the defendant’s son, his visit was not an unlawful government search and the fruits thereof were properly admitted into evidence. Accordingly, we affirm the defendant’s conviction.
Facts
Miller was indicted for and convicted of receiving stolen goods in violation of 18 U.S.C. § 2315. The events leading up to his indictment were as follows.
In November, 1980, Nandor Szombathy reported the theft of his low-boy trailer and three conveyor belts to the Spokane Police Department. In mid-February, 1981, he received an anonymous tip that his trailer was on Miller’s property in Superior, Montana. He relayed this tip to the Spokane police, who advised him to notify the FBI, which he did.
After receiving this tip, FBI Agent John Nelson notified the local sheriff’s office in Superior, Montana. A deputy sheriff then informed Agent Nelson that Miller had a low-boy with a “for sale” sign on it parked next to the frontage road running to Miller’s property. Both Agent Nelson and Sheriff Ron Boyce visited Miller’s property and examined the trailer parked along the frontage road but they were unable to confirm whether it was the stolen trailer. They then invited Szombathy to come to Superior to examine the trailer parked alongside the frontage road.
Szombathy drove to Superior on February 21, 1981. En route he drove past Miller’s property and noticed two trailers parked between the frontage road that leads to Miller’s property and the highway. The trailers were parked approximately 100 to 150 yards from the highway, and were marked “for sale.” When first driving by, Szombathy thought that one of the two trailers might have been his, but was not sure. He then continued to Superior to meet with Agent Nelson and Sheriff Boyce.
At this meeting, Szombathy asked whether he could go to Miller’s property to look for his trailer. He suggested that he pose as a prospective buyer of mining equipment to gain access to the property. Agent Nelson answered that he “didn’t see anything wrong with that at all.” The officers and Szombathy agreed to rendezvous later that morning.
Upon arriving at Miller’s property, Szombathy went to look at the trailers parked alongside the frontage road. While he was looking at the trailers, Miller’s high school-age son drove up and asked Szombathy what he wanted. Szombathy replied that he was looking for a low-boy trailer to haul mining equipment with. Miller’s son explained that there were other trailers in Miller’s shop area, and took Szombathy there. The shop area was approximately 300 to 450 yards from where the two trailers were parked.
Szombathy saw a trailer in Miller’s shop area that he recognized as his. The trailer was upside down, its axles had been removed, and its tailend had been cut off. In addition, the trailer had been painted since it was stolen. Despite these alterations, Szombathy recognized it as his because of its unusually large size and sturdy construction. Szombathy acknowledged that the trailer was not visible from the frontage road.
Upon seeing his trailer, Szombathy explained that he was looking for a smaller trailer. When Miller’s son took him into the woods near Miller’s residence, which was apart from the shop area, to look at another trailer, Szombathy saw the conveyors that had been lying on top of his trailer when it was stolen. The conveyor belts were not visible from the frontage road either.
After this visit to Miller’s property, Szombathy returned to Superior and reported his observations to the two officers at their scheduled meeting. At this point, on the basis of Szombathy’s observations, Agent Nelson suggested that they obtain a *656 search warrant. Szombathy decided that, in the meantime, he would go back to Miller’s property and photograph the stolen equipment. Agent Nelson objected to this idea, thinking that this might “tip off” Miller. Nonetheless Szombathy returned to Miller’s property to take some pictures. Agent Nelson followed him for protective purposes, positioning himself where he could watch Szombathy with binoculars.
Upon his return to Miller’s property, Szombathy encountered Miller’s son, who was leaving, and told him that he was “going back to look at the conveyor and look at the other stuff again.” Szombathy took several pictures, which were admitted into evidence at Miller’s trial.
Based on Szombathy’s observations during his visits to Miller’s property, Agent Nelson obtained a search warrant and searched Miller’s property on February 24, 1981, at which time he did not locate the stolen trailer or conveyor belts.
Miller was indicted on March 24,1981, for receiving and concealing a low-boy trailer, knowing it to have been stolen. Thereafter, Sheriff Boyce recovered the stolen trailer and conveyor belts from places other than Miller’s residence.
Prior to trial, Miller moved to suppress the evidence obtained during Szombathy’s visits to his property. He also filed a motion in limine to preclude the introduction of evidence regarding the three conveyor belts. Both motions were denied. At trial the jury returned a guilty verdict. 1
Miller subsequently moved for a judgment of acquittal or, in the alternative, for a new trial. He sought acquittal because of an alleged insufficiency of evidence. He sought a new trial because of a number of alleged errors at trial. Both motions were denied, and Miller was sentenced. He now appeals.
I
MOTION TO SUPPRESS
Miller complains that his Fourth Amendment rights were violated when Szombathy visited his property, looked around, and photographed the stolen trailer and conveyor belts. He argues that Szombathy’s contact with law enforcement agents converted his actions into government conduct, and implicated the Fourth Amendment. Invocation of Fourth Amendment protections requires both an unreasonable intrusion into privacy and a finding of governmental conduct. Neither exists in this case. Consequently, we affirm the district court’s denial of Miller’s motion to suppress.
A. The Government-Private Search Distinction
In the proceedings below, Miller moved to suppress the evidence derived from Szombathy’s visits to Miller’s property. He correctly noted that, although a search or seizure conducted by a private party does not violate the Fourth Amendment, if that individual acts as an instrument or agent of the state in conducting the search, Fourth Amendment interests are implicated.
Coolidge v. New Hampshire,
Our analysis starts with
United States v. Walther,
While a certain degree of governmental participation is necessary before a private citizen is transformed into an agent of the state, de minimis or incidental contacts between the citizen and law enforcement agents prior to or during the course of a search or seizure will not subject the search to fourth amendment scrutiny. The government must be involved either directly as a participant or indirectly as an encourager of the private citizen’s actions before we deem the citizen to be an instrument of the state....
Id. From our review of earlier cases, we discerned that two critical factors in the “instrument or agent” analysis are: (1) whether the government knew of and acquiesced in the intrusive conduct, and (2) whether the party performing the search intended to assist law enforcement efforts or to further his own ends. Id. at 791-92.
Here the government concedes that it knew of and acquiesced in Szombathy’s conduct. However, Szombathy acted out of a desire to recover his stolen property. The government argues that this consideration should conclude our analysis. We find this issue more complex.
This case involves several instances of police-private citizen contact: the invitation to Szombathy to come to Superior, the meeting in Superior when Agent Nelson gave tacit approval for Szombathy to go onto Miller’s property, and Agent Nelson’s accompanying Szombathy when he returned to Miller’s place to photograph the trailer and conveyor belts. This case also involves two alleged invasions of privacy. Given this somewhat complicated set of facts, we have found it worthwhile to consider each element of the sequence separately.
Miller complains that the government instigated the searches he complains of by inviting Szombathy to Superior. We must evaluate that invitation, however, in light of its scope and the reason it was extended. Agent Nelson merely contemplated that Szombathy look at the trailers that were parked along the frontage road and advertised “for sale.” Miller has made no showing, as was his burden, see
United States
v.
Gumerlock,
Miller also contends that Szombathy’s conduct became government conduct when the officers gave tacit approval to Szombathy’s plan to visit and gain access to Miller’s property by pretending to be a prospective trailer buyer. We reject that argument. Because Szombathy had not proposed to do anything illegal, we see no reason why the officers should have restrained him or discouraged him from visiting Miller’s property.
See generally
1 W. LaFave,
Search and Seizure
§ 1.6, at 115-17 (1978) [hereinafter
LaFave].
Moreover, the record amply indicates that it was Szombathy’s rather than the officers’ idea that he visit Miller’s property to look around. For example, at his first meeting with Agent Nelson and Sheriff Boyce, Szombathy initiated a discussion about his right to go onto Miller’s property. When the officers told him that it was up to him, he replied, “[F]ine .... I’m going to go find that trailer. That’s why I am over here.” Miller has pointed to nothing in the record to suggest that the officers encouraged Szombathy to act on their behalf, or even planted the idea of conducting a private search.
See Gundlach v. Janing,
*658
Finally, when Szombathy returned to Miller’s property to take pictures, Agent Nelson followed him for protective purposes, and from a distance, watched him take photographs. This police accompaniment did not necessarily transform Szombathy’s conduct into a government search or seizure. Upon reviewing both the intent and the effect of Agent Nelson’s actions, we find nothing that necessitates application of the Fourth Amendment. Agent Nelson followed Szombathy to Miller’s property primarily out of a concern for his safety, not out of any desire to reap the benefits of a private search.
See United States
v.
Coleman,
Our conclusion that Szombathy acted in a private capacity is consistent with the deterrent function that the exclusionary rule is designed to serve.
See generally
1
LaFave, supra,
§ 1.6 at 112-13. The record shows that the government agents were consciously concerned about offending Miller’s Fourth Amendment rights. In addition, the manner of their investigation did not create an unreasonable risk of privacy violations by Szombathy or any other private party. In inviting Szombathy to Superior, the officers acted lawfully in asking him to assist them in their investigative efforts by viewing the trailers parked along the highway to determine whether either was the stolen trailer. We need not decide what the officers’ obligations would have been if, upon arriving in Superior, Szombathy had proposed to enter Miller’s premises unlawfully, or if the officers could have reasonably foreseen an unlawful entry and such an entry occurred.
See generally id.
at 125;
Stapleton v. Superior Court,
B. Consent Search
Although we find no error in the district court’s decision that Szombathy acted in a private capacity, after reviewing the record we are also convinced that, even if Szombathy acted as an instrument of the government, Miller did not suffer an unreasonable, warrantless intrusion into his privacy. 4
In stopping to look at the trailers that were parked along the frontage road and marked “for sale,” Szombathy did nothing more than examine what had already been exposed to plain view. Only when he ventured into Miller’s shop area and the woods near his residence did Szombathy enter into areas in which Miller could possibly claim an expectation of privacy.
See generally Wattenburg
v.
United States,
[H] Miller complains that Szombathy gained access to his premises by employing a “false pretext,” i.e., by posing as a prospective trailer buyer and not disclosing the real purpose of his visit. This alleged pretext did not spoil the fruits of Szombathy’s visit.
See Lewis v. United States,
Szombathy’s second visit to Miller’s property, to take pictures, is also unassailable since it too was preceded by at least implicit consent. Szombathy testified that, upon returning to Miller’s property, he encountered Miller’s son, who was leaving, and explained that he wanted a second look at what had been shown to him previously. In the apparent absence of any objection to Szombathy’s visit, we can conclude that this “search” was similarly premised on consent.
II
MOTION IN LIMINE
Miller also contends that the district court erred in denying his motion to exclude evidence pertaining to the three conveyor belts allegedly stolen from Szombathy when his trailer was stolen. His argument is twofold: (1) introduction of that evidence interfered with his Fifth Amendment right to a grand jury indictment in that it might have caused the jury to convict him of possessing stolen conveyor belts, an offense he was not indicted for, and (2) the prejudicial effect of the evidence outweighed its probative value. The trial court denied the motion on the ground that the conveyor belts were “part of the same transaction.” We uphold the admission of that evidence.
Fed. R. Evid. 404(b) authorizes the introduction of “other crimes” evidence to help establish identity, subject only to the relevancy criteria of Rule 403.
See United States
v.
Lutz,
We find no abuse of discretion. The critical factual dispute at trial was whether the trailer in Miller’s possession was the same as that stolen from Szombathy. Evidence that Miller possessed the conveyor belts had substantial probative value because it tended to confirm that the trailer in Miller’s possession was the stolen trailer.
See United States v. White,
In addition, because the “other crimes” evidence in this case stemmed from the same transaction that was in issue, the prejudicial effect of that evidence was less than that of “other crimes” evidence that pertains to separate criminal transactions.
*660
Because only one event was in issue, the risk that the jury would infer a propensity for crime based on this “other crimes” evidence was negligible.
Cf. United States v. Two Eagle,
Miller also contends that the introduction of that evidence created a risk that he would be (and may have been) convicted for possessing stolen conveyor belts, a crime with which he had not been charged by a grand jury. In raising this Fifth Amendment challenge to the introduction of the conveyor belt evidence, Miller relies heavily on
Stirone v. United States,
Ill
TRIAL ADMINISTRATION
Miller also challenges several of the district court’s rulings during the trial. We reject these contentions.
A. Effective Cross-Examination
At the conclusion of Miller’s case, his counsel called Szombathy to the stand and upon redirect examination sought to read into evidence testimony given by Szombathy during prior proceedings regarding the dimensions of the stolen trailer. That testimony was inconsistent with his testimony at trial. The court denied this request. Miller contends that he was denied his right to effective cross-examination.
Fed.R.Evid. 611 confers discretion upon the trial court to control the mode and order of interrogation and presentation.
See also United States v. Cutler,
B. Improper Prosecutorial Remark
Miller also challenges an alleged prosecutorial reference to his silence at trial. During its closing argument, the government reviewed the evidence that tended to show that Miller had once possessed the stolen trailer. It attempted to trace the movement of the trailer from the time of its theft, to when Szombathy saw his trailer on Miller’s property, to when the trailer was found abandoned in a nearby woods. The prosecutor remarked:
When you get to the jury room, there is one question I want ... all of you [to] ask each other.... [T]he evidence is uncontradicted [that] the trailer that was found abandoned] in the woods [had been] in Howard Miller’s possession... sometime in the fall of 1980. I want you to ask yourselves, if that is so, what happened to it? What was Mr. Miller's explanation of what happened to that trailer? ...
Miller objected to this remark, and the court promptly admonished the jury to disregard any possible implication of guilt arising from Miller’s election not to testify. Miller later raised the same objection in his motion for a new trial, which the court denied. The court reasoned that, when viewed in context, the prosecutorial remark was proper because it merely preceded a reiteration of testimony regarding Millers pre-indictment explanation to a witness that he had gotten rid of or sold the trailer that the witness had previously painted for him. In other words, the prosecutor’s reference was not to Miller’s failure to testify, but to one of his pre-trial declarations.
Without deciding that the prosecutor’s remark was improper, we note that any error that may have occurred was harmless beyond a reasonable doubt. The trial court properly responded to the remark by promptly instructing the jury that it could not draw any inferences from Miller’s failure to testify.
See United States
v.
Buege,
C. Admission of Evidence
Miller also complains that the photographs of the stolen trailer that were taken after the trailer was found abandoned in a woods were inadmissible under Fed.R.Evid. 401 and 403. The admission of this evidence was proper; there has been no abuse of discretion. This evidence was relevant because it showed the alterations that had been made to the trailer since its theft and gave rise to an inference of knowledge of its theft.
See generally Gibson,
D. Jury Instructions
Finally, we reject Miller’s argument that the jury instructions necessitate reversal. Miller objected below to the court’s instruction on reasonable doubt
6
, and now argues that the court should have given a more elaborate instruction regarding the meaning of that standard when the prosecution’s case depends heavily on circumstantial evidence.
7
Miller had proposed such an instruction
8
, which was similar to that discussed in
United States v. James,
Miller also objects on appeal to the court’s failure to give an “identification instruction” similar to that discussed in
United States v. Hodges,
IV
MOTION TO ACQUIT
The district court’s denial' of Miller’s post-trial motion for acquittal was proper because, when viewed in the light most favorable to the prosecution, the evidence would enable a reasonable jury to find Miller guilty beyond a reasonable doubt.
See Jackson
v.
Virginia,
AFFIRMED.
Notes
. The jury was unable to reach a verdict at the conclusion of Miller’s first trial.
. In this portion of our analysis, we assume arguendo that Szombathy’s excursion onto Miller’s property constituted an unreasonable intrusion into Miller’s privacy. The district court seems to have made the same assumption, since it did not discuss whether Szombathy’s conduct even constituted a search.
. In Walther, as here, we found it unnecessary to decide what standard of review applies to determinations of whether a private citizen acted as a government agent for Fourth Amendment purposes. Id
. Although the issue of whether a search occurred was not raised below, i.e., the district court assumed without discussion that one had occurred, the record is sufficiently developed to permit its review. The parties were ordered to be prepared to discuss this issue at oral argument, at which time both were afforded an opportunity to do so.
. We have reviewed the other cases cited by Miller,
e.g., Jeffers v. United States,
. The jury charge on this issue was as follows:
The presumption of innocence alone is sufficient to acquit unless the jurors are satisfied beyond a reasonable doubt of the Defendant’s guilt after a careful and impartial consideration of all the evidence in the case.
It is not required that the Government prove guilt beyond all possible doubt. The test is one of reasonable doubt.
A reasonable doubt is a doubt based on reason and common sense. It’s the kind of a doubt that would make a reasonable person hesitate to act.
Proof beyond a reasonable doubt must, therefore, be of such a convincing character that you would be willing to rely and act upon it unhesitatingly in the most important of your affairs.
This instruction is in substance that at 1 E. Devitt & C. Blackman, Federal Jury Practice and Instructions § 11.14, at 310-11 (3d ed. 1977).
. The court’s instruction further provided:
There are two types of evidence on which you can properly base a verdict. One is direct evidence, that is the testimony of an eyewitness. The other is circumstantial evidence, the proof of a chain of circumstances pointing to the commission of [the] offense.
As a general rule, the law makes no distinction between direct and circumstantial evidence but simply requires before convicting a Defendant the jury be satisfied of the Defendant’s guilt beyond a reasonable doubt from all of the evidence.
This instruction is similar to that upheld in
United States v. James,
. Miller’s proposed instruction was similar to that given by the court, except that in place of the italicized language in note 6, supra, Miller would have substituted the following:
A reasonable doubt exists whenever, after careful and impartial consideration of all the evidence, you jurors do not feel convinced to a moral certainty that the Defendant is guilty of the charge. And so, if you view the evidence in this case as reasonably permitting either of two conclusions, one pointing to innocence and the other pointing to guilt, you must necessarily adopt the conclusion pointing to innocence, because so long as that is a reasonable conclusion and it exists, it would be impossible to find guilt beyond a reasonable doubt, because the very existence of a reasonable alternative on the other side would preclude you from finding guilt beyond a reasonable doubt.
This language apparently comes from
