I absolutely find this stuff appalling. It's the primary reason I'm not participating in what we do in these countries by voting for either warmonger.
But I do have to point out that some of those pictures are, in fact, not the results of drone strikes, and are actually victims of other violence.
Shakira for instance is well documented to have been the victim of a drone strike.
This girl, however, was the victim of suicide bombers in Quetta.
Our drone policy is a huge problem anyone voting for the major candidates either has to be outright ignoring or willfully justifying, but no one should need to use unrelated images to perpetuate the extent of that problem.
A: There's plenty of pictures of actual drone victims around to use (many even in your link).
B: Using people who aren't actually the victim of a drone strike is absolutely exploitative.
