1) What is the significance and/or importance of the United States Trustee Office's Handbook for Chapter 7 Trustees (hereinafter "the Handbook")?

A) Given the ample amount of recent authorities holding that several Chapter 7 trustees had acted reasonably by following the Handbook is the reverse also true?

B) That is, if a Chapter 7 trustee chooses to completely flout / ignore the requirements that are set forth within the Handbook does the trustee act unreasonably?

A) For example, can a reasonably-acting Chapter 7 trustee fail to detect the absence of the detailed explanation of purported business expenses, as required by line 16 of the bankruptcy petition's Schedule J?

3) Is circumstantial evidence alone sufficient to obtain Barton permission, when that circumstantial evidence strongly suggests that a conflict of interest (i.e. a professional and social relationship) had existed between the debtor and the Chapter 7 trustee?
