In a 19 June press release, Marc Garlasco, the senior military analyst at Human Rights Watch, declared the IDF investigation not credible, citing its complete reliance on information gathered by the IDF and exclusion of all evidence gathered by other sources. Garlasco said “"An investigation that refuses to look at contradictory evidence can hardly be considered credible. The IDF’s partisan approach highlights the need for an independent, international investigation. [...] If the Israeli allegations of tampered evidence are to be believed, many Palestinians would have to have engaged in a massive and immediate conspiracy to falsify the data. The conspirators – witnesses, victims, medical personnel and bomb disposal staff – would have had to falsify their testimony, amend digital and hand-written records, and dip shrapnel into a victim’s blood. It beggars belief that such a huge conspiracy could be orchestrated so quickly."” The press release also pointed to inconsistencies in the IDF analysis of the shell fragments.
