Who has time to send a bunch of emails and letters to the AD? Does Saul have a job?
Anyways, most people's recollection of time/events is less than what actually transpired. Example: remember that time my car broke down 2 months ago? Oh, it was 2 years ago, my bad.
So Saul's estimation of 15 emails (more like 25-30) and 1 letter (more like 5-6) would justify stalker material........
