I’m wondering if a possible explanation for one of the two cops at AG’s house leaving with a bag of groceries today could be that the family needed some supplies/toiletries/snacks but didn’t want to risk their privacy, and more importantly, their life safety, by either going to a physical store, or typing in the address for where they’re currently staying when ordering online, where it could be viewable, and thus leakable, by website staff, the personal shopper and other in-store staff, the delivery driver etc.
If there’s a policeman going to the house every day, to remove mail while wearing gloves, in case a hard-copy ransom letter gets sent there in the family’s absence, maybe the family said “We’re going to be ordering a few things from Whole Foods, with a “Leave on the doorstep” instruction. Please could you have someone bring it to our secure, unknown location when your guy goes today to get the mail?”
Just my own thoughts and opinion, but it crossed my mind as a possibility.
