Not OP but my read on this is that OP is suggesting that Israel or the US should have a recording of the rocket being fired that would have been captured by a satellite and could be shared.
Obviously there are images that have been published showing the destruction, but it’s not clear to me how looking at a picture of rubble would help to establish the origin of the rocket fire.
Given how many bombs have been dropped in Gaza (more in 6 days than the US dropped in a year of fighting in Afghanistan), it’s easy for me to imagine that the destruction of this Palestinian hospital was due to an errant Israeli bomb, but pretty difficult to imagine that a Hamas soldier with bad aim accidentally took out one of their only hospitals. From the outside, it feels like the burden of proof lies with the side that seems to be trying to flatten Gaza, not the side without access to food, water, electricity, or medical supplies.
Having said that, I sincerely doubt that this will be the last atrocity committed by either side before this is over, so I doubt that we will ever get any evidence that is truly conclusive.
