While the argument can be made that Gonzalez was unsuited for the job of Attorney General, those who may be hoping that some sort of legal charges against him might be filed are going to be disappointed.
Legal proceedings would involve his critics in proving their accusations. That would be very problematic for them.
Perhaps the most disturbing thing about this brouhaha is that, once again, a zealous investigator can come up with "conflicting testimony" from a man who is being forced to remember and defend statements made over a period of three or four years. Statements that are a small part of thousands of statements made to hundreds of different colleagues within a department of the government.
None of us could fully protect ourselves under such circumstances.
