"inconclusive" or "high probability"?
Regardless, why are we investigating this? Do we think it was intentional? A journalist shows up to a military operation against terrorists and she's KIA - what are we looking into? If the Israelis targeted an American journo? What do we think we'll find that we didn't see by watching their investigation? And if we think they got something wrong, why did it take us 6 months to throw the flag?
ETA: here's the short of it. Nothing about this investigation screams "Justice!" That's why no one here is excited about it. If it smells like poop and looks like poop, don't be the idiot who decides to see if it tastes like poop.
