Maybe the line to draw is autonomy? If you're after a mass shooter, today anyway, that would be an ROV activity: a human pilot flying it could distinguish cops, perps, and vics and fire one taser. If you ask for autonomy, then you're leaping into Slaughterbot territory (see link below someone already posted) and you might have thousands of them in a theater of operations.
