In that respect, I’m not sure that’s any different from the porch pirates following the delivery vehicles around, though - they follow the vehicle, stop when the delivery truck stops, and have time to get out and be prepared to nab the package before the delivery person eventually gets out of the truck with it. Some just nab everything, but there’s the opportunity to assess and be selective, too. Seems like it would only be definitive if they are stealing just AT&T phones, or they caught people with manifests (which it sounds like they did, in at least one instance), or they’re showing up before the delivery vehicles and waiting.
