Interesting that we've seen the consequences of this data grabbag already - how many employees of which US Fe[de]ral Agency/ies had their employment data leaked recently?
Just imagine - these US Fe[de]ral "Intelligence" Agencies are storing a pack of data about as many people as they can. They are also suspected of having bad data hygiene including of course the inevitable lax[ative] security. And no doubt a good many of these data will contain links to financial matters.
Anyone remember how The Culture wins in Consider Phlebas? Thei Minds winkled a path through the Idiran computer security, and turned the Idiran computer complex, making it in effect another Culture Mind.
So you have these huge insecure databases of nearly everyone with more than a little bit of money. You have opponents who can do their times tables. You have Check Mate before you're even aware of it.
If I were a Patriotick US Citizen I'd demand these "Intelligence" Agency folk shoot themselves in the head with dumdums. And even then I'd expect a 100% failure rate, with dumdum rounds mysteriously appearing on the foot. Unfired.
