Historically, one group of people who raid your dumpsters of recalled, out of spec products or packaging is your own employees. They know what the product is worth and everyone either nows how to or knows someone who knows how to sell the items on the internet or at flea markets.

Consider what if your packaging is stolen. Anyone can put anything in the packaging. The liability will likely fall to you, even if the packaging was stolen from your dumpster.

The best way to protect yourself is to shred anything that could hurt you if the "wrong person" got hold of it. Another threat is your competitors coming into possession of your prototypes or models. When in doubt, destroy the products.
