Taking Casts of the Monster's Footprints
If you need to prove destruction, or just want to assure yourself that hard drives aren't piling up on The Destructorator's back lawn, you'll want the following:
Destruction witnessing—watch your hard drives go to circuit board heaven
Remote viewing via video—same as above, but from the comfort of your office
Certificates of destruction—especially after you've witnessed a couple of kills
So there you have it: Leave those pliers in the Mesozoic era where they belong. The world is evolving, and there are creatures that can munch your troubles away for a song.
