Quoting

Probably not a big deal, any half wit would know that anything of a major concern wouldn't be put in an email anyway and if it was would be backed up separately.
Well, as a retired IT professional, I can say with authority that that's simply not correct. Every place I ever worked after email came along tried to use the email system as a document management system. I kept insisting that it cannot be relied on for that, document management is a separate function and if you want to do it electronically you need purpose-built software to do it safely and securely, and you need to train people to think about what they put into email and consider whether it should be preserved or not. I got exactly nowhere. A lot of email communication is trivial and doesn't need to be saved permanently, but a lot of material that now travels by email used to go in the form of typed memos and letters and there was always a copy filed in some central file registry. That doesn't happen anymore, people send stuff around and don't think about it at all, assuming the machines and the IT people who run them will take care of everything. They can't, and I saw the consequences of that repeatedly: people couldn't find information they needed because it was in the email system, not a proper document database or a central paper file system. Most organizations these days do not know what they know anymore, too much of it's in the wrong place and not properly organized or indexed.
Besides, "any half wit..." Remember we're talking about a government bureaucracy here.
