Opinion of the Court
445 U. S., at 587. We are also puzzled by the last sentence of the excerpt, where the court announces that the "usual rules" of the Fourth Amendment are inapplicable if the seizure is not the result of a search or any other investigative activity "precisely because there is no invasion of privacy." For the plain-view cases clearly state that, notwithstanding the absence of any interference with privacy, seizures of effects that are not authorized by a warrant are reasonable only because there is probable cause to associate the property with criminal activity. The seizure of the weapons in Horton, for example, occurred in the midst of a search, yet we emphasized that it did not "involve any invasion of privacy." 496 U. S., at 133. In short, our statement that such seizures must satisfy the Fourth Amendment and will be deemed reasonable only if the item's incriminating character is "immediately apparent," id., at 136-137, is at odds with the Court of Appeals' approach.
The Court of Appeals' effort is both interesting and creative, but at bottom it simply reasserts the earlier thesis that the Fourth Amendment protects privacy but not property. We remain unconvinced and see no justification for departing from our prior cases. In our view, the reason why an officer might enter a house or effectuate a seizure is wholly irrelevant to the threshold question whether the Amendment applies. What matters is the intrusion on the people's security from governmental interference. Therefore, the right against unreasonable seizures would be no less transgressed if the seizure of the house was undertaken to collect evidence, verify compliance with a housing regulation, effect an eviction by the police, or on a whim, for no reason at all. As we have observed on more than one occasion, it would be "anomalous to say that the individual and his private property are fully protected by the Fourth Amendment only when the individual is suspected of criminal behavior." Camara, 387 U. S., at 530; see also O'Connor, 480 U. S., at 715; T. L. O., 469 U. S., at 335.
