Victim meets with police, signs affidavit, prosecutor goes to judge with affidavit, warrant written specifically for those items only. Should be simple and even digital if we wanted it to be.

I guess the question would be how easy it is to fake this evidence. I don't know this tech. Could I throw my airtags in someone's bag and just take that to the police station and say look here on my phone, that's where my bags are, and then it's a he said/she said? Then the airtags aren't really adding anything to just your word "they took my bag".
