SCOTUS today struck down the warrantless search of a home and seizure of firearms.
Caniglia had a dispute with his wife, who spent the night elsewhere. Next day, she asked the police to do a welfare check on him, which they did. They subsequently entered his home and seized his firearms, on the basis that he might be a danger to himself or others, though as far as I know, that was just based on supposition.
First Circuit upheld the search and seizure under the "community care taking exclusion".
SCOTUS pretty much nuked that argument, and gave a firm 9-0 spanking to the First Circuit.
