> Shut down all armed drones. Review the entire use of them from top to bottom. This isn't a video game, there is no do-over.

To be clear, this isn't a "drone" problem per so, so much as an "airpower" one. There have been plenty of incidents where the use of manned aircraft have resulted in similar (probably) inadvertent civilian casualties -- e.g. the AH-64 attack depicted in the "Collateral Murder" video or the bombing of the Chinese embassy in Yugoslavia, not to mention all of the incidents during the Vietnam War and WW2.

There has historically been a trade-off between risk to military personnel and civilian casualties. Ironically, the best way of reducing that trade off probably involves more robots, albeit ones that gives the military options other than "shoot" and "let potential militant get away".
