Off topic, but that pic brought to mind a talk with a security guy some years back. His job was to check out computer centers' security. At one place, their security guy went on and on about how great their security was.
He told the guy to go over to some file cabinet and open the top drawer. He did so and nearly had a cow as there was what appeared to be a bundle of sticks of dynamite.
It turned out the first security guy cut up a broom handle, painted them red, bundled them up and had aother operative who was a "visitor" plant it.
He said it happened about three out of every 10 visits.
