I think that person has very strong pre-concieved notions… At this point a rock on the ground is “evidence” to them that the rock is in cahoots with Israel, because children in Gaza, because obviously.
That video is evidence of nothing, but certain death of 4 unknown people, at an unknown location, recorded at unknown point in time.
Again, disclaimer: There’s an active genocide in Gaza, performed by Israel against Palestinians. Hamas is a terrorist organisation.
