OPINION
Respondent Cordova was convicted of possession of heroin. He appealed the denial of his motion to suppress evidence seized under an allegedly invalid search warrant. The court of appeals reversed his conviction, holding that the affidavit used to secure the warrant did not provide an adequate basis from which the issuing magistrate could conclude probable cause existed to search the house where Cordova resided at the time of his arrest.
The affidavit submitted to secure the search warrant in this case stated:
1. That within the last 24 hours, Affiant has been contacted by a Confidential Informant, who advised that a subject driving a red Chrysler Cordova with Texas Plates, was currently selling heroin at a residence at 1106 South Cahoon. That Subject John Doe was from out of town and had brought the heroin in.
2. That Said Informant stated that subject was a [Sjpanish male, approximately 6-0 tall, weighing a little over 200 pounds, having black hair and did have some tattoos on his person.
3. That Said Informant did state that through personal knowledge, several heroin users had been to this residence.
4. That Said Informant has furnished information to Affiant in the past which Affiant did find to be true and correct through personal knowledge and investigation.
5. That based on the information provided by Said Informant, Affiant did drive by the residence and did observe the red Cordova which did have, a partial white vinyl roof. Description and the trailer house next to the house are the same as stated by Informant. Also, on checking utilities, it was learned that a Carol Cordova resided at this address.
The court of appeals based its determination that this affidavit was lacking on our rule of criminal procedure governing the issuance of warrants based on affidavits containing hearsay information. See SCRA 1986, 5-211(E). The court noted that our interpretations of Rule 5-211(E) have been based on the two-prong test formulated by the Supreme Court in Aguilar v. Texas,
Federal law before Gates — The reasons behind the two-prong test of Aguilar and Spinelli. The fourth amendment of the federal constitution, like Article II, Section 10 of our state constitution, strongly favors the warrant process. This process requires law enforcement officials to make a showing of probable cause before a “neutral and detached magistrate” in order to obtain a search warrant. Johnson v. United States,
is not [to deny] law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime.
Johnson,
The constitutionally mandated role of magistrates and judges in the warrant process requires them to make “an informed and deliberate” determination whether probable cause exists. Aguilar v. Texas,
Frequently, applications for search warrants depend on unnamed, confidential, police informants to show the existence of probable cause. To analyze such cases, the Aguilar and Spinelli Courts refined the basic requirement that applications for search warrants must contain sufficient detail to enable an issuing magistrate to make an independent determination of the existence of probable cause. Although an affidavit may be based wholly or in part on hearsay provided by an unnamed informant, “the magistrate must be informed of some of the underlying circumstances from which the informant concluded that [the facts were as] he claimed they were, and some of the underlying circumstances from which the officer concluded that the informant * * * was ‘credible’ or his information ‘reliable.’ ” Aguilar,
In Aguilar, the Court held an affidavit to be insufficient to support a search warrant when it stated simply that “Affiants have received reliable information from a credible person and do believe” that illegal drugs and paraphernalia were being kept at a particular residence. The Court found this affidavit lacking because it expounded neither the basis for the officers’ conclusion that the information was gathered in a reliable way nor the basis for the conclusion that the informant was credible. 2
In Spinelli, the Court explored two particular means by which a magistrate reasonably could conclude that an affidavit contained sufficient information to satisfy Aguilar’s two prongs. First, the Court noted, an affidavit that otherwise would be inadequate nevertheless may support a determination of the existence of probable cause if “it fairly [can] be said that the tip * * * when certain parts of it have been corroborated by independent sources, is as trustworthy as a tip which would pass Aguilar’s tests without independent corroboration.”
The Spinelli Court also opined that, even when an affidavit does not affirmatively state an informant’s basis of knowledge, it may be inferred that an informant who otherwise is known to be credible obtained the information set forth in the affidavit in a reliable fashion if the tip contains enough detail to be self-verifying. Id. at 417,
New Mexico’s rules of criminal procedure. In New Mexico, this Court has promulgated rules to govern the determination of probable cause for the issuance of a search warrant. Under SCRA 1986, 5-211(E), 4
“[Pjrobable cause” shall be based upon substantial evidence, which may be hearsay in whole or in part, provided there is a substantial basis for believing the source of the hearsay to be credible and for believing that there is a factual basis for the information furnished. Before ruling on a request for a warrant the court may require the affiant to appear personally and may examine under oath the affiant and any witnesses he may produce, provided that such additional evidence shall be reduced to writing, supported by oath or affirmation and served with the warrant.
(Emphasis added.) As first recognized by the court of appeals in Perea, and by this Court in State v. Turkal,
The use of the conjunctive “and” in Rule 5-211(E) clearly contemplates that an affidavit must set forth both: (1) a substantial basis for believing the informant; and (2) a substantial basis for concluding the informant gathered the information of illegal activity in a reliable fashion. It is equally clear that these requirements are formulations of the “veracity” and “basis of knowledge” tests of Aguilar-Spinelli. Moreover, we are convinced that these requirements structure the issuing magistrate’s inquiry in a manner made necessary by the affidavit’s reliance on second or third hand reports from an unnamed informant. As Justice Harlan noted, “It is not possible to argue that since certain information, if true, would be trustworthy, therefore, it must be true. The possibility remains that the information may have been fabricated.” See United States v. Harris,
Conversely, if “the conclusory allegations of a police officer, presumably [truthful] * * * are insufficient to establish probable cause [cf. Nathanson ], the conclusory allegations of a generally [truthful] informant must be insufficient as well.” Kamisar, supra at 556. “Truthful persons can be the bearers of hearsay, rumor, gossip, or bare conclusions as surely as can be liars.” State v. Jones,
The Supreme Court’s rejection of the two-prong test in favor of the “totality of the circumstances” test. In Illinois v. Gates, a four-justice plurality of the Supreme Court abandoned the Aguilar-Spinelli approach in favor of a “totality of the circumstances” test.

The Justices seem in large part to have been motivated by a conviction that some lower courts tended to apply the two-prong test in a rigid and technical fashion. They were convinced that such applications did not comport with the fourth amendment principle of probable cause, which was described as a “fluid concept— turning on the assessment of probabilities in particular factual contexts — not readily, or even usefully, reduced to a neat set of legal rules.” Gates,
Gates did recognize the continued utility of the basis of knowledge and veracity tests as factors to be considered. Id. at 230,
The New Mexico experience. We believe that what we have identified as the primary reason of the Gates plurality for abandoning the two-prong test — its application in too rigid and technical a fashion by some courts — has not proved to be a problem in our state courts’ application of the standard set forth in Rule 5-211(E). In Perea, for example, the court of appeals was careful to note that affidavits normally are “drafted by non-lawyers ... in the midst and haste of a criminal investigation, therefore, technical requirements of elaborate specificity have no proper place in a court’s evaluation.”
“(1) only a probability of criminal conduct need be shown; (2) there need be less vigorous proof than the rules of evidence require to determine guilt of an offense; (3) common sense should control; [and] (4) great deference should be shown by courts to a magistrate’s determination of probable cause.”
See also Baca,
We simply do not believe this tradition to be one of unthinking rigidity or overly technical application of the principles codified in Rule 5-211(E). Moreover, we believe these principles to be firmly and deeply rooted in the fundamental precepts of the constitutional requirement that no warrant issue without a written showing of probable cause before a detached and neutral magistrate. We are convinced that our rules, while providing a flexible, common sense framework, also provide structure for the inquiry into whether probable cause has been demonstrated. The fact that “non-lawyers” are involved in drafting applications for search warrants underscores rather than obviates the need for such structure. 8
We conclude that our present court rules better effectuate the principles behind Article II, Section 10 of our Constitution than does the “totality of the circumstances” test set out in Gates. Accord, State v. Jones,
Affidavit failed to state adequately the basis of informant’s knowledge — deficiency not cured by independent corroboration. Turning to the affidavit at issue in this case, we agree with the court of appeals that it fails to establish probable cause. We disagree, however, that the affidavit fails because it does not set forth adequately the affiant’s basis for believing the informant to be credible. Rather, it fails because it did not provide the issuing court with a substantial basis for believing that the information provided was reliable. Since this affidavit contained both hearsay information from an informant and corroborating facts from independent police investigation, we follow the lead of Spinelli and analyze, first, the sufficiency of the hearsay report standing alone and, second, whether the facts corroborated by the police cured any deficiencies in the report.
The court of appeals noted that the affiant, while stating that his informant had provided reliable information in the past, did not say “when the informant had provided such information, how frequently, or whether the information provided related to a matter under criminal investigation * * *. [F]or all we know, the statement could refer to nothing more than the fact the informant had correctly provided * * * the time of day * * Slip op. at 4. The state argues in its petition for certiorari that it was not necessary for the affiant to detail the information given in the past by the informant. We agree with the state that “technical requirements of elaborate specificity have no proper place in a court’s evaluation” of probable cause, Perea,
Here, the affidavit stated that the. informant had provided information in the past which the affiant “did find to be true and correct from personal knowledge and investigation.” It is true that this unadorned statement did not provide a particularly strong basis on which to judge the informant’s credibility. Cf. Turkal,
Unaddressed by the court of appeals, however, was whether the affidavit, standing alone, adequately stated the informant’s basis of knowledge for the allegation that Cordova was selling heroin. The informant reportedly stated that Cordova had brought heroin into town and was selling it at the house in question. However, the affidavit is devoid of any indication of how the informant gathered this information. Similarly, although the affidavit states the informant has personal knowledge that “heroin users” have been at the residence, there is nothing in the affidavit to indicate the source of his knowledge, or even how the informant knows the persons in question to be “heroin users.”
In Spinelli, the Court held the assertion that Spinelli was a known “gambler and associate of gamblers” was “but a bald and unilluminating assertion of suspicion that is entitled to no weight in appraising the magistrate’s decision.”
We also do not believe the affidavit contained sufficient detail concerning the alleged illegal activity to be self-verifying. Aside from a simple assertion that the heroin was brought to town by respondent, the only details in the affidavit concern a description of a man, a house, and a car parked outside that house. As with the details provided by the informant in Spinelli, which stated no more than that Spinelli spent a large amount of his time in an apartment that contained two phones with separate, identified numbers, the details provided in this affidavit relate to innocent facts that do not, either separately or taken as a whole, suggest illegal activity.
The affiant’s independent corroboration did not serve to establish the reliability of the informant’s report. See State v. Jones,
Here, the affiant verified only the informant’s description of the house and car. 9 We agree with the court of appeals that the affidavit in essence “asked the magistrate to believe the informant was reliable merely because the house and car existed, and further asked the magistrate to believe that because the house and car existed, the man and the heroin probably did as well.” Slip op. at 6. We hold that the affidavit in this case did not establish a substantial basis for believing the informant’s report was based on reliable information as required by Rule 5-211(E) and the New Mexico Constitution. Accordingly, the decision of the court of appeals is affirmed. IT IS SO ORDERED.
Notes
. Because our holding today is based on our interpretation of the New Mexico Constitution, we do not consider as controlling the principles announced in Gates or the other federal precedent cited in the body of this decision, albeit the reasoning of those opinions informs our result.
. In many cases, the affidavit will attempt to satisfy the basis of knowledge and veracity tests by stating that the informant has a reliable "track record” with the police, and that the informant gathered the information from firsthand observation. In other cases, the credibility of an informant may be assumed when the tip constitutes an admission that the informant was involved in the illegal activity. See Perea,
. The Spinelli Court compared the extent of detail in the case before it to that in Draper v. United States,
. Rule 5-211 governs procedures in district court; however, identical provisions govern the determination of probable cause in applications for search warrants made in magistrate courts, see SCRA 1986, 6-208(F); in metropolitan courts, see SCRA 1986, 7-208(E); and in municipal courts, see SCRA 1986, 8-208(F).
. In Massachusetts v. Upton,
. Other concerns of the Gates plurality, not discussed in the body of this opinion, include the concern that, if courts subject affidavits to great scrutiny, police may resort to warrantless searches, and the concern that rigid application of Aguilar-Spinelli unduely diminishes the value of anonymous tips in police work.
.For example, the Gates plurality asserted that if an informant has a particularly good track record in predicting certain types of criminal behavior, it should not stand as an absolute bar to a determination of probable cause that the affiant has failed thoroughly to set forth the basis of this informant’s prediction in a particular case.
. Cf. Gates,
. We do not address the state’s contention that the police also verified the description of Cordova himself, as this did not take place until after the warrant issued. It is well settled that probable cause cannot be established by the results of the search. State v. Baca,
