So why did the first links I clicked both mention other Kiwi's getting arrested before their trial for possessing CSAM?

One New Zealander has been arrested and five identified as “suspects” after Europol and German police shut down one of the largest child sex abuse online platforms in the world.

[...]

He said that to date, a 24-year-old man has been charged with possessing child exploitation material and is set to appear at Timaru District Court on May 13.

Edit: Removed second link as it was a NZ'er in AUS.

Edit 2: Here's some more examples however of people being arrested after finding CSAM on their devices.

Maybe I'm just a dumb Aussie, but please help me wrap my head around why it seems to be different rules for a former deputy police commissioner?
