What does the "plain view" doctrine allow law enforcement to do?

The "plain view" doctrine permits law enforcement officers to seize evidence of a crime that is clearly visible to them without needing a warrant, as long as they are in a location where they are legally allowed to be. This principle is founded on the idea that if an officer is lawfully present and sees something in plain sight that is evidently connected to criminal activity, it is reasonable for them to seize that evidence immediately. The requirement is that the officer must be in a lawful position to observe the evidence and it must be immediately apparent that the item is evidence of a crime or contraband.

This doctrine balances the need for law enforcement to effectively combat crime with the protection of individuals' Fourth Amendment rights against unreasonable searches and seizures. It enables officers to act promptly on evidence without the delay that might be associated with obtaining a warrant, ensuring that crime-scene preservation and public safety are maintained.
