Hiatt-
Some time ago a very wise person told me, "you can't control what they put in your file".
They haven't done any damage to you yet.
They are either trying to make you aware of a "problem" or they are trying to scare you.
Until they supply you with an armed guard to guard your trucks after you leave, you really can't control what gets thrown on your trucks after you leave.
I wouldn't worry about it. They enjoy seeing you all torn up inside.
