A similar situation I heard about; a local pizza shop used to have a policy that if an order is messed up, the staff would be allowed to eat it for free. They then changed it so that all messed up orders would have to be thrown directly in to the trash. A waste of that pizza, but they found that order messups reduced dramatically when the staff were not allowed to eat the "mistake". It's the same situation here. You brick a few stolen items and it prevents future theft since there is no longer a reward for it.
