What is an affidavit mainly used for in law enforcement?

An affidavit is primarily used in law enforcement as a sworn statement that provides the necessary legal grounds for actions such as search and seizure. When law enforcement officers seek a warrant to conduct a search of a property, they must present an affidavit to a judge or magistrate. This affidavit contains factual information that supports the claim that there is probable cause for the search. The officer signing the affidavit affirms under oath that the information contained within it is true to the best of their knowledge. This sworn nature of the document is crucial, as it provides a level of accountability and legal weight to the claims made.

The other options, while they pertain to law enforcement documentation, do not capture the central legal purpose and function of an affidavit in the context of obtaining warrants for searches or seizures.
