You have to understand discipline in the IRS, it is inverse to grade level. Secretaries are probably on the lower end of the scale, perhaps GS5-7 or so. Meanwhile, the big cheese at the SES or higher G levels like 14 or 15 would get a slap on wrist for things those at the bottom get fired over. For instance, how about those who owe back taxes? Why even the former chief of the treasury, his less than honorable lil timmy Gaitner was a tax cheat and still got the job plus got to stay on once it was announced.
Who audits the IRS?
