This summary is not the rule. The rule text controls.
When a judge is deciding whether to approve a search warrant, they can ask for more than just written affidavits. The judge is allowed to listen to spoken testimony from the officer or person requesting the warrant, as long as that person swears to tell the truth first.
If the judge does take this spoken testimony, it can't just disappear after the conversation. The law requires that everything said be recorded, written down right away, and added to the official file along with the affidavits. This creates a paper trail so there's a clear record of everything the judge considered before approving the warrant.
This matters because it protects people's rights. If someone later questions whether a search warrant was properly issued, the recorded testimony gives courts a way to check exactly what information the judge had and relied on when making that decision.
