> Aren't assassinations targeted by definition?

Sure. I should have said assassinations and targetted attacks. The video shows the ability to target specific races/genders/demographics.

> The drone is just a delivery mechanism for the ordinance, and good luck getting your hands on that.

I don't know why a shotgun cartridge could not be used in place of a shaped charge. Just pop down to your local Walmart.

You seem to be arguing that this work speculative fiction isn't interesting because we already have a huge number of ways to kill people, and that it's not currently possible. The point of this sort of fiction is to get us to imagine a world where these things are possible, where it is achievable.
