It's hard not to form opinions regarding behavior. What is a rational person to think when classified information is found on a home brew server and nothing comes of it? Was that server subpoenaed and searched by the FBI? No. Did the FBI conduct a dawn no-knock raid of the home to search for documents/computers/etc. that contained classified information? No. Did legal advisors, also under investigation, to the person who concocted the home brew server have their home(s) raided and searched? No. Those persons were also given legal immunity. Did the FBI record any interviews with the people connected with the improper handling of classified information? No. Again, the legal counsel that was under investigation that was given legal immunity also served as legal counsel to another person under investigation. Were any indictments brought about after requested phones and computers were destroyed by those that were under investigation? No. Lastly, does the legal statute governing the prosecution for improper handling of classified information contain the word "intent" anywhere within it? No. A common thread through this process and the lack of prosecutorial interest happens to be a couple of names who happen to be investigators with the power to drive the scope and direction of the investigation. I'm sure that it's just coincidence.
If you have any doubt of this, I would suggest you duplicate the home brew server in your house and store some classified information on it. Tip off the FBI and let us know how that works out.
