In this criminal case, this Court granted certiorari to review the Court of Appeals’ unpublished opinion in State v. Missouri, 97-UP-448 (Ct.App.1997). We affirm.
Factual/Procedural Background
During January and February 1995, Greenville detectives were investigating a crack cocaine ring with the help of a confidential informant. On February 3, 1995, the police obtained a search warrant to search the home of Laura and Curtis Sibert a/k/a “Hot Sauce” for cocaine. The lead detective, Eric Cureton, submitted an affidavit in support of the search warrant. The affidavit states, in part:
Your affiant [Eric Cureton] states that on January 25, 1995 he received information from investigator Sam C. Cureton of the Greenville County Sheriffs Office pertaining to Victor Wyatt Missouri. The information that was relayed to your affiant that Missouri was involved in the manufacture and distribution of crack cocaine. The following is a chronological chain of events leading to your affiants [sic] belief that Victor Wyatt Missouri, and others not yet identified, are manufacturing and distributing crack cocaine....
The confidential source of information, who from here forward will be referred to as CSI, stated that for the past two months he has purchased a total of two kilograms of cocaine *551from Victor Missouri. He would receive this in half kilo quantities every two weeks.
On January 31, 1995 CSI stated that he had talked with Missouri and another subject who is only known as “Hot Sauce.” During this conversation Missouri and “Hot Sauce” stated that they were going to Atlanta, Georgia on February 1, 1995 and obtain four kilos of powder cocaine. This cocaine would then be delivered to Greenville, South Carolina and cooked into crack cocaine. On February 1, 1995 this same CSI went by “Hot Sauce’s” apartment at 400 Summit Drive apartment 5-D, Summit Place Apartments. During a conversation with “Hot Sauce” CSI was told that he had not been able to leave for the trip to Atlanta, that they had some things to get together beforehand. During this same conversation CSI told “Hot Sauce” the he wanted to purchase from him a half of a kilo. “Hot Sauce” told CSI that it would cost him around $13,000.00 for the half kilo. CSI told “Hot Sauce” to call him when he left for Atlanta. On February 2, 1995 at 4:00 in the afternoon, CSI went to Missouri’s residence at 126 Sycamore Drive in the City of Greenville, South Carolina. At the residence was Missouri and “Hot Sauce.” “Hot Sauce” told CSI that he was leaving for Atlanta around 4:30 and would return around midnight that same night. “Hot Sauce” told CSI that he would page him as soon as he got back in town.
On February 3,1995, at 4:00 in the morning, Missouri called CSI and told him that “Hot Sauce” was back and they needed somewhere to cook the crack. He said he couldn’t cook it at his (Missouri) house because he had relatives there. CSI told him he would give him an answer later and he ultimately told him no. Around 9:00 this same morning CSI paged “Hot Sauce” via his digital pager. “Hot Sauce” returned the call and told CSI they were still trying to get it together. At 10:15 another page was made to “Hot Sauce” with the same results. At 2:00 in the afternoon the CSI drove to “Hot Sauce’s” apartment at 400 Summit Drive and went in to inquire about his portion of the cocaine. Your affiant wired the CSI with a body transmitter that would enable your affiant to monitor the conversations he had while inside this apartment. Your affiant, while monitoring the audio transmitter, heard a male voice, whom CSI later *552stated was “Hot Sauce”, question CSI about the phone that had been used earlier trying to, set the transaction up. This male appeared to be somewhat reserved about talking with CSI about the cocaine. CSI told your affiant that “Hot Sauce” did appear to be nervous about the deal they were trying to make. “Hot Sauce” told CSI that he had the crack but he would call him when it was right.
While officers of the Vice and Narcotics Bureau were surveilling 400 Summit Drive, Apartment 5-D on February 3, 1995, it was determined that Missouri, “Hot Sauce” and others who have not been identified, were in the apartment. Around 5:00 a black male and black female left the apartment in a white dodge van.... The vari then traveled to Parkersway Foods at Worley Road and Rutherford Road. The female again went inside. After the female left Detective Sergeant T.D. Christy interviewed the clerk and he stated that the black female had purchased 5 boxes of Arm & Hammer baking soda. The van then traveled back to apartment 5-D and the female took a grocery bag into the apartment. She returned to the van and they left again. The surveillance on the van was terminated at this time. Your affiant, through training, experience and working with other experienced investigators, believes that Victor Wyatt Missouri, “Hot Sauce” and others yet unknown are manufacturing crack cocaine inside of apartment 5-D Summit Place Apartments, 400 Summit Drive in the City of Green-ville, South Carolina.-
When the police executed the search warrant, officers found Missouri in the kitchen standing over a sink, facing a set of triple beam scales. Inside the sink was a quantity of cooked, crack cocaine. Missouri was arrested for trafficking in crack cocaine. At his trial, Missouri moved to suppress the evidence obtained in the search. Missouri argued the affidavit supporting the search warrant contained false information and further omitted critical, exculpatory information. The trial court denied the motion to suppress. In an unpublished opinion, the Court of Appeals reversed the trial court, holding that the omitted information was necessary for the magistrate’s finding of probable cause. See State v. Missouri, 97-UP-448 (Ct.App.1997). Judge Hearn dissented in a separate opinion. This Court granted certiorari to address the following issue:
*553Did the Court of Appeals err in applying the test articulated by Franks v. Delaware1 for considering a challenge to the veracity of a search warrant affidavit?
Law/Analysis
The State argues that the Court of Appeals improperly applied the Franks test in deciding whether the magistrate had probable cause to issue the search warrant. We disagree.
At the suppression hearing, Officer Cureton testified that the following sentence in the warrant affidavit was in fact a false statement: “ ‘Hot Sauce’ told CSI that he had the crack but he would call him when it was right.” Officer Cureton stated that Curtis Sibert a/k/a “Hot Sauce” never told his informant there was crack in Hot Sauce’s apartment. Further on cross-examination, Officer Cureton testified that his informant had gone into Hot Sauce’s house at about 3:00 p.m. on February 3, and the informant was told that Missouri had the “stuff,” but it was not there. The informant then left the residence and returned at about 4:00 p.m. after Missouri had returned to the house. A “wire” had been placed on the informant’s body to enable the police to listen to the conversations. After the informant left Hot Sauce’s house, he approached Officer Cureton and told him, “It’s not there. It’s not there.” In addition, Hot Sauce had earlier told the informant that he did not want to cook the cocaine at his house because his wife was trying to go straight. This information was not provided to the magistrate in the supporting affidavit. The trial judge concluded that even with this information, the magistrate would have had a substantial basis upon which to find probable cause for issuing the warrant.
In Franks v. Delaware, the United States Supreme Court held that the Fourth and Fourteenth Amendments gave a defendant the right in certain circumstances to challenge the veracity of a warrant affidavit after the warrant had been issued and executed.2 To summarize, the Court provided the following two-part test:
*554(1) To mandate an evidentiary hearing, the challengers’ attack must be more than conclusory and must be supported by more than a mere desire to cross-examine. There must be allegations of deliberate falsehood or of reckless disregard for the truth, and those allegations must be accompanied by an offer of proof; and
(2) If these requirements are met, and if, when material that is subject of the alleged falsity or recklessness disregard is set to one side, there remains sufficient content in the warrant affidavit to support a finding of probable cause, no hearing is required.
Franks, 438 U.S. at 171-72, 98 S.Ct. at 2684, 57 L.Ed.2d at 682.
Franks addressed an act of commission in which false information had been included in the warrant affidavit. However, the Franks test also applies to acts of omission in which exculpatory material is left out of the affidavit. See, e.g., United States v. Colkley, 899 F.2d 297 (4th Cir.1990); United States v. Vazquez, 605 F.2d 1269 (2d Cir.1979). To be entitled to a Franks hearing for an alleged omission, the challenger must make a preliminary showing that the information in question was omitted with the intent to make, or in reckless disregard of whether it made, the affidavit misleading to the issuing judge.3 There will be no Franks violation if the affidavit, including the omitted data, still contains sufficient information to establish probable cause. See Colkley, supra.
*555The instant case involves both an act of commission and an act of omission by Officer Cureton in drafting the warrant affidavit. We find that Officer Cureton at least acted recklessly in making the false statement and in omitting the exculpatory information. He testified unequivocally that the statement was false, and his informant had, in fact, made a statement to the contrary. Thus, the primary issue before this Court is whether excluding the false information and inserting the exculpatory statement, there remains a substantial basis upon which the magistrate could have found probable cause to issue the warrant. In doing so, this Court must apply the “totality of the circumstances” test of Illinois v. Gates, 462 U.S. 213, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983). See Colkley, supra.
The supporting affidavit begins with the allegation that Victor Missouri and others “are manufacturing and distributing crack cocaine.” The affidavit then discusses a series of chronological events which are intended to support this prefatory allegation. The affidavit’s description of the informant’s contact with the suspects on the day the search warrant was obtained culminates with the false statement that Hot Sauce told the informant he had the crack but would call him when it was right. If our task were simply to consider the affidavit without this statement, we would likely find a substantial basis for probable cause. The absence of the false statement makes the location of the drugs less certain, but this uncertainty is negated by the other events recounted in detail in the affidavit.
However, under Franks, our inquiry does not end here. We must also consider the effect of adding the informant’s statement, “It’s not there,” as well as the information that Hot Sauce did not intend to cook the cocaine at his apartment. In doing so, we hold that the affidavit would not support a finding of probable cause to search Hot Sauce’s apartment.
We begin with the presumption that the Fourth Amendment does not require an affiant to include all potentially exculpatory evidence in the affidavit. See Colkley, supra. A presumption to the contrary “would perforce result in perniciously prolix affidavits that would distract police officers from more important duties and render the magistrate’s determina*556tion of probable cause unnecessarily burdensome.” Colkley, 899 F.2d at 303. However, in the instant case, the omitted information goes to the very heart of the affidavit’s purpose, which is to establish probable cause to search Hot Sauce’s apartment for crack cocaine. Instead of simply creating some uncertainty in the affidavit, the inclusion of the omitted information creates an affirmative hurdle which the remaining portions of the affidavit must overcome. These other portions reveal that the suspects had arranged to sell a quantity of crack cocaine to the confidential informant. The suspects purchased cocaine in Atlanta and transported it to Greenville for this purpose. The affidavit further reveals that the suspects purchased baking soda and brought it back to Hot Sauce’s apartment. Baking soda is known to be a common cutting and drying agent when converting powdered cocaine into crack cocaine. Standing alone, these facts are not conclusive as to the presence of crack cocaine in Hot Sauce’s apartment, but they make it a fair probability. Yet, when the omitted information is inserted, the probable presence of the crack cocaine in the apartment is defeated. This, in turn, erodes the basis upon which a magistrate could find probable cause to search Hot Sauce’s apartment. The remaining portions of the affidavit fail to rehabilitate this basis.4
We realize this case presents a close call on the probable cause determination. However, the combination of the police officer’s deliberate falsehood and his omission of critical facts pollute the affidavit to the extent that a magistrate could not have found that probable cause existed to issue the search warrant. There is no doubt that the officer intended to mislead the magistrate in obtaining the search warrant. We realize that police officers routinely leave out facts they believe are immaterial to the probable cause determination. *557Yet, when an omission is combined with an affirmative falsehood, it reveals that the affiant not only believed the omitted information was critical, but that a statement in the affidavit to the contrary was necessary for establishing probable cause. We recognize that under Franks our role is not to punish dishonest police officers but, rather, to ensure that a substantial basis exists to find probable cause. That said, the depth of the prevarication perpetrated by the officer in this case undermines any remaining legitimacy the affidavit might possess. Under these circumstances, this Court is required by the Constitution to invalidate the search warrant where the facts create such a close call on the probable cause determination.
Conclusion
Based on the foregoing, we AFFIRM the Court of Appeals.
MOORE, J., concurs. FINNEY, C.J., concurs in result only. BURNETT and WALLER, JJ., dissenting in a separate opinion.. 438 U.S. 154, 98 S.Ct. 2674, 57 L.Ed.2d 667 (1978).
. In State v. Sachs, 264 S.C. 541, 216 S.E.2d 501 (1975), this Court also addressed whether a defendant could attack the veracity of facts sup*554porting a search warrant when the warrant was valid on its face. Noting that the United States Supreme Court had not yet squarely addressed this issue, this Court answered the question in the affirmative, providing the following limited test: "Did the officer, or other government official, in such capacity, intentionally, recklessly, or in bad faith recite facts he knew or should have known to be erroneous, without correcting the error by additional affidavit or affirmation, to obtain the issuance of a warrant?" Sachs, 264 S.C. at 555, 216 S.E.2d at 509. The Court further provided the following caveat: "However, even if the officer was delict, so long as probable cause was established by affidavit or affirmation without the aid of the erroneous fact, the warrant satisfies the constitutional demands.” Id.
. See Edward Gregory Mascolo, Controverting An Informant’s Factual Basis for a Search Warrant: Franks v. Delaware Revisited and Rejected Under Connecticut Law, 15 Q.L.R. 65 (1995).
. The cases cited in Judge Hearn’s dissent are inapposite to the instant case because they do not involve the reckless or intentional omission of material facts. Rather, these cases deal with the constitutionality of including in the search warrant affidavit reconnaissance information gathered from thermal imaging machines. In addressing this issue, the cases found that even without the thermal imaging information, there was sufficient information in the affidavits to support a finding of probable cause. See United States v. Cusumano, 83 F.3d 1247 (10th Cir.1996); United States v. Robinson, 62 F.3d 1325 (11th Cir.1995); United States v. Ishmael, 48 F.3d 850 (5th Cir.1995).
