Peace -

In order to maintain "traceability of evidence," should they ever actually discover anything of significance, virtually all communication by the CIA, FBI, and Secret Service is done "face-to-face." The most you'll get out of an email or phone call is a visit - if they think something is important enough to follow up.

They seem to have no objection to surreptitiously obtained hearsay, but the agent conducting an investigation has to be able to "personally identify" anyone interrogated. Difficult to do by 'phone or email.

Your emails undoubtedly are in their files, as one of the major complaints against their existing databases is that once something gets put in it cannot be removed even if they find out that it's wrong.
