Might make sense, yeah. How many computers would get blown up during such a test, and how much productivity would be lost and how much money would it cost? What is the expected cost of a major breach or malware infection? How much less likely does a breach or malware infection become as a result of leaving one of these laying around? I actually wouldn't be surprised if leaving these did come out positive, in much the same way that regular fire drills come out positive.
