The United States appeals from the district court’s suppression of information gained through wiretaps. The district court relied on
Franks v. Delaware,
FACTS
On November 3, 1982, the district court issued an order allowing the government to intercept certain wire communications. The government’s application for the order was supported by an affidavit of Ralph E. Lumpkin, Special Agent, FBI, that included the following statements that the court, in subsequent hearings, found false or misleading:
118. The confidential informants referred to in the above paragraphs have all stated that they would not testify regarding the information they furnished to the Federal Bureau of Investigation because they fear retaliation to themselves or their families. The La Cosa Nostra, including the Los Angeles organized crime family, has had a reputation since the 1930’s for reprisals against anyone who does not respect their demands or who would testify concerning illegal activity.
119. In addition, none of the sources utilized in this affidavit are familiar with *1484 all the various aspects of the criminal enterprise and electronic surveillance is therefore, the only method of obtaining evidence as to all of the various criminal activities.
At the suppression hearing it was developed that Hanophy, informant number 2, was working with agent Schettino, a former FBI agent in a Miami drug investigation involving Ippolito. Although Hanophy told FBI Agent Lumpkin and another agent, Sadler, that he would not testify in the California case because he feared Ippol-ito, it became apparent that this assertion was not entirely true. Rather, it developed that Agent Schettino had told Hanophy to say that he could not testify so that his refusal could be used to demonstrate the necessity of a wiretap in the California case. The testimony at the suppression hearing also established that Hanophy was willing and probably able to infiltrate the entire California conspiracy.
It is true that at the time of Hanophy’s meeting with the FBI Agents, Hanophy was not aware of the involvement of several of the co-conspirators later indicted in this case. However, Hanophy testified that he had been an important part of Ippolito’s importing schemes, that Ippolito wanted Hanophy to go to Colombia to help arrange for the drug connection, and that he knew the identity of some of the other co-conspirators at the time he was asked if he would testify. Hanophy also testified that he had expressed his willingness to have his conversation about the drug deals monitored and to draw conspirators out into the open where they could be brought under surveillance. Schettino characterized Hanophy’s former involvement with Ippolito as being his “right hand man” and testified that at one point, when Hanophy was acting as an informant, Ippolito had asked Hanophy if he would run his operations while Ippolito served an up-coming prison term.
The district court found that the government had made intentionally false, reckless or misleading statements in paragraphs 118 and 119. The court then determined that a reasonable district court judge could have denied the wiretap application if the offending paragraphs were omitted and the affidavit was examined to see if there was necessity for the wiretaps or, alternatively, if the paragraphs were replaced with the truth and the affidavit was examined to see if there was necessity for the wiretaps. Accordingly, the district court found that the false statements and factual omissions were material and that suppression was required.
DISCUSSION
A. Standard of Review
The application of
Franks v. Delaware
to wiretap orders presents a question of law and therefore should be reviewed
de novo. See Christensen v. United States,
B. Franks Materiality
The district court found that the government made intentionally false or misleading statements in order to persuade the court that a wiretap was necessary. The court also found that the challenged statements and omissions were material to obtaining the wiretap order. It followed that the wiretap evidence should be suppressed. The Government does not seriously challenge the fact of intentional deception, but disagrees that the deception called for suppression.
In
Franks v. Delaware,
the Supreme Court determined the circumstances in which it is appropriate to suppress evidence derived from a warrant issued on the basis of an affidavit that contained false
*1485
statements concerning probable cause. This circuit has not previously had occasion to apply the
Franks
analysis to false statements concerning the necessity for a wiretap sought by the government pursuant to 18 U.S.C. § 2518. The
Franks
court held that the reviewing court should set the affidavit’s false assertions to one side and then determine whether the affidavit’s remaining content is still sufficient to establish probable cause. If the affidavit is not sufficient, the warrant must be voided and the fruits of the warrant suppressed.
Franks
emphasizes the importance of truthful information to the neutral detached magistrate who must determine whether there is probable cause.
Id.
Title 18 U.S.C. § 2518(1)(c) provides that each application for a wiretap authorization shall include:
a full and complete statement as to whether or not other investigative procedures have been tried and failed or why they reasonably appear to be unlikely to succeed if tried or to be too dangerous.
Title 18 U.S.C. § 2518(3)(c) provides that in issuing a wiretap authorization order, the district court must determine whether:
normal investigative procedures have been tried and have failed or reasonably appear to be unlikely to succeed if tried or to be too dangerous.
These two sections together make up the so-called necessity requirement for granting a wiretap order. The statutory language suggests that before finding that a wiretap is necessary, the court must find that alternative methods have been tried or would not have succeeded.
See United States v. Martinez,
C. Materiality of False Statements
The district court found that although the government had tried some alternative methods of investigation, it had misled the issuing judge about the willingness of a particular informant to testify and about his ability to uncover evidence of the conspiracy using only conventional techniques. Therefore, it is necessary to evaluate the hypothetical effect of knowledge of the existence of a potentially useful informant on *1486 the original district court’s determination that a wiretap was necessary. If it would have no effect, then the misstatement would not be material.
Generally, the government must overcome the statutory presumption against granting a wiretap application by showing necessity.
See United States v. Giordano,
we must be careful not to permit the government merely to characterize a case as a “drug conspiracy” ... that is therefore inherently difficult to investigate. The affidavit must show with specificity why in this particular investigation ordinary means of investigation will fail.
United States v. Robinson,
Beyond the requirement of specificity, we have expressly adopted a practical and common sense approach in determining the sufficiency of government wiretap affidavits.
See Abascal,
In the case before us, the government has tried certain alternatives, but has failed to pursue others that easily suggest themselves and are potentially productive and not unduly dangerous. Certainly one of the options of the issuing judge would have been to deny the application because necessity was not shown.
Although the government need not pursue every alternative means of investigation, neither should it be able to ignore avenues of investigation that appear both fruitful and cost-effective. It is not unreasonable to expect the government to utilize those methods that appear to be potentially productive. We would flout the statutory intent that wiretaps be used only if necessary, were we to sanction a wiretap simply because the government pursued some “normal” investigative strategies that were unproductive, when more fruitful investigative methods were available. In effect, the government would be able to secure a wiretap in every case, even where a normal strategy would be likely to achieve the same result without resort to the serious intrusion that a wiretap necessarily entails.
Applying the Franks analysis in this case, we must delete the falsity from the original affidavit (both paragraphs 118 and 119) and insert instead the finding of the reviewing court 1 that there was an informer who was both willing to testify and had great potential for uncover *1487 ing the entirety of the conspiracy under investigation. 2
We conclude that a reasonable district court judge could have denied the application because necessity for the wiretap order had not been shown. Therefore, suppression was properly ordered.
Because of the result we reach, we need not decide whether we should affirm the decision for reasons of governmental misconduct alone. 3
AFFIRMED.
Notes
. Although the
Franks
decision itself only deleted the false material in the affidavit, several
*1487
courts have recognized that
Franks'
reasoning should logically extend to material omissions,
see United States v. Dennis,
. Hanophy testified that he was willing to testify but was told that he should say he would not. Moreover, there is ample evidence in the record of the suppression hearing, and the reviewing district court found, that Hanophy had tremendous investigative potential and that he was not in danger. He was a former close associate of Ippolito, was involved in the plan to obtain a boat to move drugs from Colombia to the west coast, had been asked by Ippolito to run his operation, and had already met a couple of the members of the conspiracy and would probably meet more if he went to Colombia as requested by Ippolito. On the other hand, there was some evidence, though the reviewing district court found it unconvincing, that Hanophy was not completely trusted by Ippolito, that Hanophy would not have attained a high rank in the organization and that he consequently might be exposed to some danger. Yet, whether we adopt the district court’s factual finding or whether we view the evidence as open to some interpretation, the result is unchanged because a reasonable judge could decide there was no necessity.
. The result would be the same under the materiality test in which the court simply deletes the falsity and then determines whether the issuing court would still issue the wiretap order. Under this test paragraphs 118 and 119 would be deleted as misleading. The remainder of the affidavit describes the investigative techniques used by the government, states that they had not yielded adequate information and states further that the bulk of the government’s information had come from informants. The affidavit would no longer contain the statements that the informants would not testify or that their continued use would not be effective. Under the reasonableness test of
Spagnuolo,
it would appear that while “normal” means of investigation have been tried, there is no showing that those means have been unsuccessful or that other means would be unlikely to be successful or too dangerous. Moreover, the eviscerated affidavit would now lack the showing of specific circumstances rendering normal investigative techniques ineffective.
