In BP v. Mayor and City Council of Baltimore the court held that where defendant energy companies premised 28 U. S.

In Caniglia v. Strom the court held that neither the holding nor logic of Cady v. Dombrowski justifies the removal of Caniglia’s firearms from his home by police officers under a “community caretaking exception” to the Fourth Amendment’s warrant requirement.
