From a jumble of secret reports, damning data on big banks and dirty money

This is the initial report. For some of the key analyses and takeaways, you can see them all on this part of the ICIJ's website: https://www.icij.org/investigations/fincen-files/

Not to belittle the quality of the reporting and research by the ICIJ but a hefty chunk of the site's narrative about hiding funds puts way too much often unsubstantiated focus on how evil and "dirty" the whole thing is, as a default position, which is not entirely healthy or particularly honest in philosophical terms, mainly because it by default implies that government having a right to snoop and intervene into every facet of private financial transactions is an inherently good thing.

It is not. Governments regularly engage in nefarious and dishonest financial dealings on a scale many private entities don't come close to matching. Governments also often terribly squander vast sums of public finances that they managed to squeeze from the private world, and yes, there is a very valid argument or two in favor of financial privacy being a necessary thing in the modern world, instead of just viewing it as something that automatically comes with criminal connotations just because some owners of assets seek to keep the nature and movement of theirs private.

>on occasions an address in China would have Switzerland’s “CH” country code assigned to it

Switzerland's country code is CH? TIL...

The first "damning" sentence throws out a sensationalistic claim about "bloodshed and suffering".

This is not mentioned again in the article, is certainly not substantiated in the article, and doesn't look like it's substantiated anywhere else on the site, either.

Sensationalist much?

Has this been fact-checked by a third party? How do we know this isn't more foreign disinformation to erode trust in our financial institutions? The documents could be forgeries.
