What is mandatory for a search warrant when describing the evidence sought?

The requirement for a search warrant to advise on specific known items is essential because it establishes probable cause and provides a clear description of what law enforcement seeks to obtain. This specificity helps ensure that the search is not overly broad and respects the Fourth Amendment rights against unreasonable searches and seizures. By detailing the items in question, the warrant allows the executing officers to understand precisely what they are authorized to search for and seize, thereby helping to protect those rights.

Requiring a detailed description also serves to limit the scope of the search, ensuring that it does not extend beyond the items specified in the warrant. This not only safeguards the privacy rights of individuals but also upholds the integrity of the judicial process by ensuring that any evidence obtained is within legal bounds and can be admissible in court.
