Well, Koskinen swore under oath that Lerner's HD was destroyed, as well as several others of interest.
Here's a thing I remain curious about. There has been talk about a six month cycle in which tape backups are over written. I have heard no talk about off site storage - where is the vault and what is in it?
Hard drives from the laptop can be destroyed, as well we all know now. But offsite storage is required, and to keep them for many years, many times at least 10 years, is the norm, sometimes longer. Wherever the email server for the IRS is located is where you’ll find backups of every email she’s written.
