Your solution itself is very simple, but getting everyone in a neighborhood to agree to put out fake packages is very difficult.<p>Also, a cardboard box that&#x27;s left outside as a decoy for several days would soon deteriorate, and would need to be replaced in order to look realistic (a soggy old box on a dry day wouldn&#x27;t be convincing).
