The obvious response is that Gaza is a very densely populated place, of course there's civilians near any given location, that's not a conspiracy by Hamas. But are there any other talking points I should hit?
(I'm not really a lib in rehab, but this seems like the comm for getting talking points straight)
"Are you really telling me that Hamas, upon hearing the whistle as an incoming shell or missile from the IDF, rushes to grab the nearest civilian and wraps themselves up in them snugly like some sort of human blanket in order to protect themselves from ordinance that can level entire buildings? Seriously?"
