What the ‘plain view’ cases have in common is that the police officer in each of them had a prior justification for an intrusion in the course of which he came inadvertently across a piece of evidence incriminating the accused. The doctrine serves to supplement the prior justification-whether it be a warrant for another object, hot pursuit, search incident to a lawful-arrest, or some other legitimate reason for being present unconnected with a search directed against the accused-and permits the warrantless seizure. Of course, the extension of the original justification is legitimate only where it is immediately apparent to the police that they have evidence before them; the ‘plain view’ doctrine may not be used to extend a general exploratory search from one object to another until something incriminating at last emerges.
