What must search warrants include?

Search warrants must include the statutory grounds for issuance, which is essential because it provides the legal basis for why the warrant is being sought. This includes an explanation of probable cause, detailing why law enforcement believes that evidence of a crime will be found in the specified location. The presence of statutory grounds is not only a requirement to ensure that the warrant is issued legally but also serves to protect individuals' Fourth Amendment rights against unreasonable searches and seizures.

Providing this information helps to ensure judicial oversight in the warrant process and maintains checks and balances on law enforcement authority. It is crucial for ensuring that warrants are not issued arbitrarily or without sufficient justification based on law.

The other options do not meet the necessary legal criteria for what must be included in a search warrant. While estimated time for execution might be relevant in some situations, it is not a legal requirement. Details on previous warrants or a command from the highest authority may provide context or hierarchy but do not substantively contribute to the legal foundation of the warrant itself.
