This. Caniglia has nothing to do with red flag laws.
But we have had some big cases come down in the last week with Caniglia addressing "community caretaking" function in the context of residences; Edwards v. Vanoy holding that Ramos v. Louisiana (state criminal jury trials must be unanimous) does not apply retroactively; and finally, the Texas Supreme Court's holding in Ex parte RPGP, that expunction eligibility for misdemeanor charges is offense based, not arrest based, as all the courts of appeals have previously held, meaning if a person is arrested for misdemeanor A, B, and C, and A and B are dismissed, the defendant can have records relating to A and B expunged. The law used to be that if you were arrested for 100 charges, and you pled to 1, and 99 were dismissed, you were ineligible for an expunction of anything.
I like the facts of Caniglia, we've all been there at one time or another.
During an argument with his wife, petitioner Edward Caniglia placed a handgun on the dining room table and asked his wife to “shoot [him] and get it over with.” His wife instead left the home and spent the night at a hotel. The next morning, she was unable to reach her husband by phone, so she called the police to request a welfare check. The responding officers accompanied Caniglia’s wife to the home, where they encountered Caniglia on the porch. The officers called an ambulance based on the belief that Caniglia posed a risk to himself or others. Caniglia agreed to go to the hospital for a psychiatric evaluation on the condition that the officers not confiscate his firearms. But once Caniglia left, the officers located and seized his weapons. Caniglia sued, claiming that the officers had entered his home and seized him and his firearms without a warrant in violation of the Fourth Amendment. The District Court granted summary judgment to the officers. The First Circuit affirmed, extrapolating from the Court’s decision in Cady v. Dombrowski, 413 U. S. 433, a theory that the officers’ removal of Caniglia and his firearms from his home was justified by a “community caretaking exception” to the warrant requirement.
Held: Neither the holding nor logic of Cady justifies such warrantless searches and seizures in the home. Cady held that a warrantless search of an impounded vehicle for an unsecured firearm did not violate the Fourth Amendment. In reaching this conclusion, the Court noted that the officers who patrol the “public highways” are often called to discharge noncriminal “community caretaking functions,” such as responding to disabled vehicles or investigating accidents. 413 U. S., at 441. But searches of vehicles and homes are constitutionally different, as the Cady opinion repeatedly stressed. Id., at 439, 440– 442. The very core of the Fourth Amendment’s guarantee is the right of a person to retreat into his or her home and “there be free from unreasonable governmental intrusion.” Florida v. Jardines, 569 U. S. 1, 6. A recognition of the existence of “community caretaking” tasks, like rendering aid to motorists in disabled vehicles, is not an open-ended license to perform them anywhere.
