James Edward Colkley and Jamison Henry Johnson appeal their convictions for bank robbery, 18 U.S.C. § 2113(a), bank larceny, 18 U.S.C. § 2113(b), and assault during a bank robbery, 18 U.S.C. § 2113(d). Johnson contends that the district court should have suppressed incriminating post-arrest statements made by him because the affidavit submitted in support of the warrant for his arrest did not contain certain potentially exculpatory information known to the affiant. In addition, both aрpellants maintain that the trial judge improperly excused a jury member during trial and impermissibly admitted certain evidence.
We hold that the Johnson affidavit was not tainted by the affiant's failure to include within it all potentially exculpatory information. Johnson’s incriminating statements were properly admitted because Johnson made no showing that the affiant intended to mislead the magistrate by omitting information, and because the warrant with the omitted information would in any event have been supported by probable cause under the “totality of the circumstances” test articulated in
Illinois v. Gates,
I.
On May 5, 1988, two armed men robbed the Baltimore Federal Financial Bank in Pikesville, Maryland. One of the robbers held up the lobby tellers, while the other robber took money from the bank vault. Bank officials reported to police authorities that the robbers stole $71,442, and that their take also included 32 twenty-dollar bait bills and several malfunctioning dye packs.
Based on bank surveillance photographs and interviews with eyewitnesses, the F.B.I. developed composite descriptions of the two robbers. Appellant Colkley became a suspect based on one of the composite descriptions and his past bank robbery activity.
On May 23, an anonymous informant telephoned the F.B.I. to report that appellants Johnson and Colkley had told him that they recently robbed a bank in Baltimore County. The informant’s account of this robbery was remarkably consistent with the robbery at Baltimore Federal Financial. The informant stated that Johnson stole money from the vault while Colk-ley held up the lobby tellers. He also said that the robbers had taken a dye pack that failed to operate. Finally, the informant reported that a reliable associate had seen over $60,000 in Johnson’s house during May 1988.
Based on this information, agents began surveillance of Johnson’s home in June 1988. They observed two cars parked outside Johnson’s home which they determined belonged to Johnson’s brother and Colkley. An investigation revealed that Colkley purchased his car the day after the bank robbery for $4,780 in cash which he had removed from a brown envelope containing more cash. The agents also learned that Johnson’s brother, accompanied by John *299 son, had purchased a car four days after the robbery for $2,551.50 in cash. In addition, on June 14 an agent conducting surveillance observed Johnson purchase a van for $3,100 in cash. An examination of the cash used in this purchase disclosed one of the bait bills taken in the robbery.
In the meantime, investigators prepared two identification photospreads containing six pictures each. Colkley’s photograph was in one photospread, Johnson’s in the other. Two eyewitnesses positively identified Colkley as the lobby robber, and two others' said he “looked similar” to the lobby robber. None of the six eyewitnesses were able to identify Johnson, however; three identified other individuals in the Johnson photospread as similar to the vault robber, and three could identify no one.
On June 23, 1988, a United States Magistrate issued separate warrants for the arrest of Colkley and Johnson. The warrant applications were accompanied by affidavits executed by Special Agent Thomas Moore of the F.B.I. Both affidavits contained eyewitness descriptions of the robbery, composite descriptions of the two suspects, an account of the surveillance of Johnson’s home and the information gained by investigating the automobile purchases, and a summary of the photospread identifications of Colkley. In addition, the Johnson affidavit included information learned from the anonymous informant. The Johnson affidavit did not recount that the eyewitnesses failed to identify Johnson in the photospread.
Colkley and Johnson were arrested separately. Police arrested Colkley in the car he purchased the day after the robbery. An inventory search of the car revealed two handguns which were later introduced at trial. Johnson was arrested at his residence. After initially disavowing knowledge of the bank robbery, he made numerous incriminating statements concerning his involvement in it. In response to an agent’s question about the location of the robbery money, he replied “I had my fun, I am broke.” Confronted with evidence of the bait bill discovered during his purchase of the van, he stated, “the van got me.” Finally, he told an agent, when I get out of jail I would have learned, and I won’t make the same mistake again.” A subsequent search of Johnson’s home revealed a .38 caliber bullet that was admitted at trial.
Prior to trial, Johnson challenged the affidavit used in support of his arrest warrant. He claimed that the affidavit was defective because it failed to note that numerous witnesses did not identify him in a photographic spread, and because agent Moore based the composite height description of the vault robber — allegedly Johnson — on the testimony of only one witness and in disregard of the testimony of other witnesses who claimed that the vault robber was shorter. Based on these allegations, Johnson requested and received an evidentiary hearing under
Franks v. Delaware,
On November 16, 1988, a jury returned guilty verdicts against both Colkley and Johnson for bank robbery, bank lаrceny, and assault during a bank robbery. 18 U.S.C. § 2113(a), (b), & (d).
Colkley and Johnson appeal their convictions.
II.
We first address the district court’s refusal to exclude Johnson’s incriminating post-arrest statements. We agree with the district court that the omitted information in the affidavit did not require suppression of these statements. We reach this conclusion by different means, however, and hold that the district court need not have held a Franks hearing on the integrity of the *300 affidavit because there was no substantial preliminary showing thаt the affiant intended to mislead the magistrate, and because inclusion of the omitted information would not have defeated probable cause in any event.
A.
In
Franks v. Delaware,
If a
Franks
hearing is appropriate and an affiant’s material perjury or recklessness is established by a preponderance of the evidence, the warrant “must be voided” and evidence or testimony gathered pursuant to it must be excluded.
Id.

B.
The district court granted Johnson’s request for a Franks hearing based on its conclusion that
Johnson has made a strong showing that the FBI agent who applied for the warrants intentionally omitted the information in the warrant application that none of the six eye witnesses identified Johnson. There was an omission of fact that the court regards as an important fact. ... [T]he omission ... may have affected the outcome of the magistrate’s probable cause determination.
The district court held that agent Moore’s omission of the Johnson photospread information satisfied the “intent” prerequisite to a Franks hearing without considering whether Moore intended the omission to mislead the magistrate or omitted the information in reckless disregard of its misleading effect. Johnson argues on appeal that the district court’s decision to hold a Franks hearing was correct because intentional оmission is all that this element of Franks requires.
We think this formulation fails to capture the meaning of
Franks
or the realities of the warrant application process. Affidavits “are normally drafted by nonlawyers in the midst and haste of a criminal investigation.”
United States v. Ventresca,
*301
Franks
clearly requires defendants to allege more than “intentional” omission in this weak sense. “The mere fact that the affiant did not list every conceivable conclusion does not taint the validity of the affidavit.”
United States v. Burnes,
This case presents a question of omission rather than commission on the part of the agent. While omissions may not be
per se
immune from inquiry,
see United States v. Owens,
Here Johnson made no showing, and the district court possessed no evidence, that agent Moore had the requisite intent to mislead. The most that the record here reveals about Moore’s failure to include the photospread information is that he did not believe it to be relevant to the probable cause determination. At the very worst, he was merely negligent in disclosing all relevant considerations to the magistrate. His acts fell far short of the level of flagrant police action Franks is designed to prevent, and a hearing under that decision was not required.
Nor could the district court have inferred intent or recklessness from the fact of omission itself. Some courts have recognized this type of inference if the omitted material was “clearly critical” to the finding of probable cause.
See United States v. Martin,
C.
Neither the оmitted information nor the allegedly skewed composite height description was material to the probable cause determination. For this reason also, a Franks hearing was not required.
The district court misstated the type of materiality that
Franks
requires. It believed that the affiant’s omission was material because it “may have affected the outcome” of the probable cause determination. However, to be material under
Franks,
an omission must do more than potentially affect the probable cause determination: it must be “necessary to the finding of probable cause.”
Franks,
In determining whether the affidavit with the omitted information would be supported by probable cause, we must apply the “totality of the circumstаnces” test of
Illinois v. Gates,
The Johnson affidavit including the omitted data still contains more than ample information to establish probable cause to arrest Johnson. The affidavit stated that Colkley was a suspect in the robbery based on photographic identification and past robbery activity. The car Colkley purchased with cash the day after the robbery was detected outside Johnson’s home. In addition, Johnson himself was involved in cash purchases of two cars within a month of the robbery. The second car was paid for with one of the bait bills taken during the robbery. Finally, the Johnson affidavit recited the informant’s tip to the police that Johnson had admitted committing a bank robbery that bore a remarkable resemblance to the one at Baltimore Federal Financial. Although the informant was anonymous, his tip was sufficiently detailed and sufficiently corroborated by independent police work to come within the standards of probable cause articulated in
Gates,
The inclusion of the photographic identification informatiоn does not affect this probable cause to arrest Johnson. The inability of any of the witnesses to make a positive identification on the Johnson pho-tospread, and the inconsistencies in witness identifications of those individuals who looked “similar” to the vault robber, undercuts any exculpatory value in the photo-spread information. And to the extent that the Johnson photospread information has exculpatory value, it is not enough to defeat probable cause when weighed against the informant’s tip and Johnson’s car purchase with a stolen bait bill.
Finally, inclusion of all the testimony concerning the vault robber’s height does not affect the probable cause determination. Not surprisingly, witness testimony concerning the vault robber’s height varied, with estimates ranging from 5'6" to 5'10". These small discrepancies in height lack significance in the probable cause determination, particularly in light of the other evidence that points to probable cause to arrest Johnson.
III.
In addition to being unsupported by the logic of Franks, Johnson’s contention that the Fourth Amendment requires an affiant to include all potentially exculpatory evidence in the affidavit must be rejected on more general grounds.
In effect, Johnson asks us to import the rule of
Brady v. Maryland,
We must be cautious, however, about importing the panoply of
Brady
protections from trial practice into warrant application proceedings. The
Brady
rule derives from due process and is designed to еnsure fair criminal trials.
Bagley,
There are other differences in the duties imposed by
Brady
and
Franks.
The con
*303
stitutional obligation to disclose material exculpatory information in the
Brady
context attaches regardless of the intent of the prоsecutor, and constitutional error can be found without a demonstration of moral culpability.
Agurs,
Moreover, a requirement that all potentially exculpatory evidencе be included in an affidavit would severely disrupt the warrant process. The rule would place an extraordinary burden on law enforcement officers, who might have to follow up and include in a warrant affidavit every hunch and detail of an investigation in the futile attempt to prove the negative proposition that no potentially exculpatory evidence had been excluded. It would perforce result in perniciously prolix affidavits that would distract police officers from more important duties and render the magistrate’s determination of probable cause unnecessarily burdensome. In addition, a broad duty of inclusion would turn every arrest or search into a warrant contest. Such consequences would, in turn, discourage reliance on warrants, a result the Supreme Court has stated should be avoided in shaping Fourth Amendment doctrine.
Gates,
In short, a rule requiring affiants to disclose all potentially exculpatory information has nothing to recommend it. Unless the defendant makes a strong preliminary showing that the affiant excluded critical information from the affidavit with the intent to mislead the magistrate, the Fourth Amendment provides no basis for a subsequent attack on the affidavit’s integrity.
IV.
The defendants raise several further issues that fall within the district court’s discretion. First, they contend that the district court should not have excused a member of the jury without an evidentiary hearing to determine the juror’s fitness. However, the district court clearly did not abuse its discretion in ruling that the juror’s failure to appear for thirty minutes of testimony warranted substitution without further inquiry.
See United States v. Corsino,
Defendants next argue that the district court should not have admitted evidence of the handguns found in Colkley’s car аnd the .38 caliber bullet found in Johnson’s home. Defendants claim that the guns and bullet constitute “other bad acts” evidence under Fed.R.Evid. 404(b). But the evidence was probative of the crimes charged against defendants, not other bad acts. It was thus admissible.
Finally, the trial court did not abuse its discretion in admitting evidence of Johnson’s sudden acquisition of wealth after the bank robbery. Such evidence is relevant and generally admissible, especially when, as here, there has been a showing that the defendant was impecunious prior to the crime.
United States v. Pensinger,
*304 V.
For the foregoing reasons, the judgments of conviction are
AFFIRMED.
