> I’d like to offer the point of view that if the drones become better and more surgical in their precision, it would reduce civilian casualties.

It would reduce collateral casualties per target attacked, which would make the drones easier to use with looser target selection criteria, which might both increase number of targets attacked and increase the number and ratio of incorrect-target-selection casualties.

The law of unintended consequences is most likely to sneak up and bite you when you only bother to consider first-order effects.
