An added layer of oversight to prevent what has never happened before? Ok, I guess that could be helpful. TBH, I dont know the process for ordering drone strikes, but I think it would literally take someone (General level?) going completely rogue, somehow seizing control of a drone (that is often being operated from across continents) and then executing a foreign national. Not impossible, but you are more likely to be killed by a falling cow imo.
That sounds scary to me.
