How so? Presumably packages are generally stolen after they've been delivered? So their photo proves it was on my porch, but it doesn't disprove that someone came along and stole it shortly after it was delivered... (my camera provides that video, however).
I once got a delivery notification, and when I got home he package wasn’t there. I thought someone stole, but then I read on the delivery notes that the package was put inside the mailbox.
It was 24 cans of soda and several other items. No way it was actually delivered that way.
So either it wasn’t and the delivery person lied, maybe to still get the delivery as completed (and therefore paid or count against a quota), or it was delivered and then stolen. I had no idea what it was, but called Amazon saying that I never received the package, and mentioned its delivery notes said the very large package was put inside the mailbox, clearly impossible. They re-sent my order promptly.
My point is that it’s super easy to say “hey Amazon you never delivered, send it again”. The picture is for the consumer as much as it is for Amazon, now they have irrefutable evidence that the package was in the right place for a while.
Ah, that makes more sense. Yes, since delivery drivers can have impossible quotas / inefficient-but-mandatory routes etc. they have been known to throw things over fences etc., requiring a photo 'on the porch' does counter that (if not the rest of the catch-22).
