MEMORANDUM **

Vargem appeals his conviction for possession of a machine gun, 18 U.S.C. §§ 922(o) and 924(a)(2), and possession of an unregistered firearm, 26 U.S.C. §§ 5841, 5861(d), and 5871. He contends, first, that the district court erred in denying his motion to suppress and, second, *581 that the district court erred in denying him a Franks hearing. Franks v. Delaware, 438 U.S. 154, 98 S.Ct. 2674, 57 L.Ed.2d 667 (1978). 1

1. The district court did not err in holding that the magistrate judge who issued the search warrant had a “substantial basis to conclude that the warrant was supported by probable cause” that evidence of a crime would be found at Vargem’s residence. See United States v. Fernandez, 388 F.3d 1199, 1252 (9th Cir. 2004) (internal quotation omitted). Vargem’s two arguments to the contrary fail. First, the magistrate judge could reasonably have inferred from the warrant affidavit that Var-gem had been informed of a restraining order prohibiting him from possessing firearms at his home or elsewhere. Officer Tuell stated in the warrant affidavit that he had “verified with V[argem]” that Vargem was the subject of a restraining order, and that the restraining order required him to surrender all firearms. The remaining facts in the affidavit permitted the inference that some of the many firearms that Vargem possessed were still in his safe at home. See Cal. Fam.Code 6383(e) (2010) (“The law enforcement officer’s verbal notice of the terms of the [restraining] order shall constitute service of the order and is sufficient notice.”); Illinois v. Gates, 462 U.S. 213, 240, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983) (holding that, in judging the facts before him in a warrant affidavit, a magistrate may draw “the usual inferences which reasonable men draw from evidence”) (internal quotation omitted).

Second, Vargem’s argument that California law did not authorize the search warrant misses the point. The question, for the purpose of the Fourth Amendment, is whether there was probable cause to believe that Vargem was violating the law and probable cause to believe that evidence of this violation would be found at his home. Whether the warrant was authorized under state law regulating the issuance of warrants is irrelevant. See California v. Greenwood, 486 U.S. 35, 43, 108 S.Ct. 1625, 100 L.Ed.2d 30 (1988) (“We have never intimated ... that whether or not a search is reasonable within the meaning of the Fourth Amendment depends on the law of the particular State in which the search occurs.”).

2. The district court did not err in refusing Vargem a Franks hearing as Vargem has failed to make a “substantial preliminary showing” that any statement in the warrant affidavit was false, let alone knowingly or recklessly so. 438 U.S. at 155-56, 98 S.Ct. 2674. Vargem argues that Officer Tuell’s statement in the warrant affidavit that the restraining order required him to “surrender all firearms” was knowingly or recklessly false; under California law, a party once restrained must “relinquish” all firearms. Cal. Fam.Code § 6389 (2010). We see no material difference between the words “relinquish” and “surrender.”

AFFIRMED.
