TNT here in the UK sent me a picture of someone else's driveway. I know several ex Amazon delivery guys who said other couriers used to keep a store of random driveway photos on their phone if they were nicking the parcel. Deliveries were GPS tagged so they'd turn up, open the app and enter the photo and then just drive on
Basically the bosses at courier companies dont (and probably cant) check that the photo corresponds with the address. These drivers actively look for doorbell cameras and cctv too. If there is surveillance they're less likely to steal.
It probably takes 15 seconds to put the address into street view and have a look around. Shouldn't be too dificult to validate the photo. Not sure if there are any privacy policies preventing that, but I doubt it.
