Suppose that a defendant is charged with possessing fentanyl with the intent to sell it. The state’s evidence includes a Facebook direct message, purportedly from the defendant to an informant, saying “just got some China Girl, you want any?” An officer took a photograph of the direct message as it appeared on the informant’s smartphone, and everyone is satisfied that the photograph fairly and accurately depicts the message. But the defendant objects to the introduction of the message on the grounds that there’s no way to be sure that he wrote it. How might the state respond?
