Omitted facts for Franks purposes are intentional in one sense, but not presumably intentionally misleading. Not every thing the affiant knows makes it in there. Also, citizen informant’s statement defendant was seen with a gun five weeks before the search warrant was issued was not stale. United States v. Hammonds, 2019 U.S. Dist. LEXIS 148291 (W.D. N.C. Aug. 30, 2019):
When relying on omitted facts from a search warrant affidavit to show its deceptiveness rather than an affirmative false statement, a defendant faces an even greater burden. United States v. Clenney, 631 F.3d 658, 664 (4th Cir. 2011) (citing Tate, 524 F.3d at 454-55). The Fourth Circuit has recognized that an affidavit drafted by non-lawyers submitted in support of a search warrant application “cannot be expected to include … every piece of information gathered in the course of an investigation”; resultingly, any decision to omit information is “intentional” in that it was done knowingly. Tate, 524 F.3d at 455 (quoting Colkley, 899 F.2d at 300). However, “Franks clearly requires defendants to allege more than ‘intentional’ omission in this weak sense.” Colkley, 899 F.2d at 301. “To obtain a Franks hearing the defendant must show that the omission is the product of a ‘deliberate falsehood or of reckless disregard for the truth.'” Id. (quoting Franks, 438 U.S. at 171). The information omitted from the warrant affidavit must also be material. Id. “For an omission to serve as the basis for a hearing under Franks, it must be such that its inclusion in the affidavit would defeat probable cause for arrest.” Id. (citation omitted).

… Defendant does not make a “detailed offer of proof’ that Investigator Von Hackney intentionally or recklessly omitted information from the October 2015 interview, and without more than bare and conclusory allegations, Defendant cannot carry his heavy burden. …
