I’ve experienced this on several occasions with FedEx packages sent from Canada to Switzerland (care packages from my parents back home). FedEx routes everything through Memphis and in those cases, packages were opened (and several items were damaged, incl a handmade blanket on one occasion)) by overzealous U.S. customs agents. Recourse? None.US customs is checking outbound packages? Why do they care about what's leaving the country? Isn't their job to secure things coming in? So strange.
