The Killer Robots have arrived

It's a mistake to give these machines lethal weapons. If a physical deterrence is required then give them a nonlethal acoustic weapon. By choosing to make these systems lethal people will put far more effort into defeating them.

Since these models use huge amounts of bandwidth (4 real time video feeds per SWORD?) RF jamming will be the first strategy. The nature of the beast is that the weapon will have to get better so the next logical development is to give the weapon platform the ability to operate autonomously. Then we have automated killing machines (a.k.a. Terminators) running around the world.
