There is reason to question the Drone program, and the military vets know it. Remember the administration running this program—they have no respect for the lives of their own citizens. I’m not saying don’t use drones, but if you had more knowledge of the actual targeting practices you might change your mind about wanting more. Military vets have likely had access to information you haven’t. We are killing shepherds and many other innocent people based on faulty intel in many cases. Some day we may reap what we’ve sown.
Q
Very good points; I wasn't involved in the drone programs when I was in, but my understanding is that they did (at least at the time) have to have affirmative ID and affirmative permissions much like a sniper. (Now, I readily admit that my info was 2nd/3rd hand and, even if accurate, SOP could have changed since then.)
That said, there've been statements to the effect that the President has authorization from Congress for (a) indefinite detention, and (b) [lethal] drone operations against US citizens. (Interesting note: an amendment to the NDAA prohibiting usage of drones against US Citizens was introduced, but not passed into law — perhaps like domestic espionage there are currently [non-lethal?] drone operations against Citizens.)
