Which part are you trying to be careful with believing? The dead bodies are on camera.

If the part in question is who killed them, there are multiple witnesses saying it was Israeli forces. But let’s assume they are all lying, or were deceived by Hamas: why would Hamas interrogate and kill Palestinian women and children? If anything, they would use them as body shields, no? They can hide out in schools and hospitals so that in order for Israel to attack them, they’d have to kill innocent people too. And to think Hamas would do it to make Israel “look bad” seems interesting. It’s not like any war crime charges are going to be brought to Israel. Maybe they want more citizens of other countries to get riled up to get their governments to stop funding Israel, but that seems like a lot of forethought for Hamas, no? And to also guarantee all the witnesses would claim it was Israeli forces?

Does it not make more sense for it to have just been Israeli forces? Do you sincerely believe some Israeli troops would never do such a thing?
