They've raised a damage report prior to delivering the package.

I could do this for any package that comes in from usps and claim they damaged it so I never received it?

If you didn't receive the "package", you obviously cannot claim It was damaged.

At times, photos are taken of the damage at the depot as well as the weight of the package - which they can refer to during an Investigation. But what happens to the package after It leaves the depot (on Its way to the buyer's address), Is a different story. Given It's already damaged, the goods could've been stolen before It was dropped off at Its destination.
