Can you really blame people for being skeptical of Palestinian government official death toll figures? They have a pretty strong incentive to lie, just like the Israelis do similarly. I mean, “everyone in the playground we blew up was an Islamic Jihad Terrorist” is the similar kind of info I’d expect from the IDF.
Even moreso, only a week or two ago there was that hospital explosion that video evidence pretty solidly showed was Palestinian rocket launch that failed while it was ascending and killed that courtyard full of people, and yet they still stubbornly insist was an Israeli airstrike.
Both sides have made utterly ludicrous claims (the rendered video of the tunnel network is the latest example) and should taken with a hefty grain of salt.
