>Independent 3rd parties were brought in to verify, though.

Reuters was given an IDF escort as they were walked through the tunnel system, during which a room with some servers was called a Hamas data centre, and they nodded along. That's not quite the same thing.

>Lots of the footage in the early days of the war that was claimed to be from Gaza was actually recycled from the Syrian civil war.

Lots of footage that Hamas or advocates for Palestine released or Twitter randos? Not all of those things are equivalent to Israel making a claim.
