After what condition must a search occur for an anticipatory search warrant?

The correct choice is centered around the principle governing anticipatory search warrants, which are issued based on the prediction that certain evidence will be found at a particular location after a specified event occurs. In this case, the search must take place when the explicit triggering event stated in the warrant occurs. This condition is essential because it provides the legal basis for the search, ensuring that law enforcement only acts when there is a reasonable expectation that the evidence described in the warrant will be present at the designated location.

Anticipatory warrants are designed to balance the need for law enforcement to act swiftly with the constitutional protections against unreasonable searches and seizures. Therefore, proceeding with the search before the triggering event is not permissible, as it undermines the warrant's validity. Understanding this condition is crucial for ensuring that any search conducted under an anticipatory warrant adheres to legal standards and upholds the integrity of the judicial process.
