Biometric gun lock boxes are for sale on, of course, Amazon.

You're right about other primates -- about chimps, anyway. "Chimp throws rocks" on YouTube yields lots of clips, some in captivity, some in the wild. The ones from the Goodall Sanctuary carry the stamp of authenticity; the others look real too. Not all the chimps are good shots, but the same can be said of a lot of humans.
