to be clear, this was not a direct LEO mandate.
I got the same response from talking to techies at a large telco, they kept the records just in case they needed them (not for any specific LEO use, but just in case they needed the info at some point in the future), and because it was easier to keep them than to delete them. In other words, throwing a few more drives into a server farm was relatively straightforward compared to figuring out what to delete, when, under what conditions, and how (lots of different formats, data all over the place, etc). (This issue isn't unique to telcos, it seems to be near-universal, it's always easier to keep data lying around than to figure out what to delete). Peter.
