I thought that just meant that the records were obtained from the provider through a court order. I'm betting there is an expert on that witness list who can explain them with a degree of accuracy to a jury.I believe the you are correct that the defense intends to refute the conclusions of LE about the cell phone evidence, but "PEOPLE’S NOTICE OF INTENT TO INTRODUCE SELF-AUTHENTICATING DOCUMENTS (P-12)" dated 8-19-2019 was agreed upon by both legal teams in the hearing, and verbally approved by the judge. It states that the cell phone records will be introduced as self-authenticating documents, not requiring expert testimony to verify. IMO
