I like that idea Ben.

We've been doing that ever since we domesticated dogs (sic'em Fang!!).

One of the major drawbacks was when one's favorite dog got killed / injured in the process.

With a Robo-Fang, no need to worry about grieving its loss/injury while doing it's job.

Unless one has a really loyal and spunky one like R2-D2, then that would be a hard loss to handle. I'd think twice about sic'ing R2 on someone hazardous...

Maybe they could program irritating personalities to the drones so one wouldn't be too broken hearted when it got trashed... I'd send C3-PO into a minefield in a second!
