After Defendant Mackenzie Becker apparently discharged a firearm during a
road-rage incident, police executed two search warrants for an address associated
with Defendant and found evidence used to convict him of firearms and drug charges.
He now argues that the district court erred in denying his motion to suppress that

evidence because the affidavit supporting the first warrant did not sufficiently link
the road-rage incident to the address searched by the officers. He also contends that
his conviction as a felon in possession of a firearm must be reversed because the
statute of conviction, 18 U.S.C. § 922(g)(1), violates the Second Amendment.
We affirm. The affidavit established probable cause that evidence of the road-
rage incident would be found at the searched house. One could reasonably infer that
the house was a residence of Defendant’s because a search of law-enforcement
databases attributed the address to him, and police surveillance corroborated the
attribution: the car Defendant drove during the incident was parked in the house’s
driveway and he was observed washing his car there and entering and exiting the
house. Also, one could infer that Defendant would keep the firearm at his residence.
That three weeks passed between the incident and the application for the warrant did
not undermine that inference. And Defendant’s Second Amendment challenge is
foreclosed by this court’s precedents.
I. BACKGROUND
The alleged road-rage incident occurred on February 13, 2023. Detective
Gerald Sloan of the Denver Police Department investigated the incident. Detective
Sloan’s affidavit for a search warrant described as follows the results of the
investigation:
The victim told officers that he observed a driver commit several egregious
traffic violations while merging onto the interstate. When the victim pulled alongside
the other driver to “speak” with him, the driver brandished a firearm. R., Vol. 1 at 37.
