There is no way you or anyone else besides those within the agencies themselves would be able to qualify on what data and for what reasons the US assassinates anybody.

We do know, they assassinate people though. And I'd argued that is already incompatible with democratic and humanist values

That's a defeatist attitude. If you care about changing something, you must discuss it and take action against it.

There are some things which fighting against is not worth the effort. Concentrating on things which can create significant positive change is much more fruitful.

Teach me Master!

Ok so, how about concentrating on ending the fruitless killing of foreign civilians based on cellphone metadata? Would that be good?

Maybe that'd engender less ill will against the US government in those and other communities, creating a significant positive change?

Oh, I'll get right on that, then!

Right after I invent cold fusion and stop sarcasm on the internet! (Besides which, I do not believe anyone can know why secretive agencies in governments assassinate people, if you had been reading...)
