The 4th Amendment.

Explanation:

The 4th Amendment of the U. S Constitution ensures the right to privacy and freedom from unreasonable governmental searches and seizures. It provides the citizens to be secure from any unreasonable search or seizure.

The Fourth Amendment guarantees protection against any unreasonable searches by government, however, upon a probable cause, the government may search without a warrant. Therefore, an anticipatory warrant may be issued based on probable cause to believe that evidence of a crime, while not currently at the place described, will likely be there when the warrant is executed. Only through this provision, the government may search without a warrant.
