Might those be the same "certified and vetted sources" that obtained and published Oboingo's college transcripts, demanded justification for intervention in Libya, clamored to see the documents and relevant information relating to Fast and Furious and Benghazi?It would be a double standard if in the course of the US presence the killing of civilians was an intentional act and the plan was solely to kill those civilians.
And it is in many cases. Don't forget about Obama's policy of double taps with his drones.
Kindly reference you assertions with certified and vetted sources where those drones are intentionally targeting civilians together with the plans clearly state such.
Oh, wait.....
