On one hand, we understand completely it was deliberate misconduct, and was likely done for two main reasons: First, she wished to avoid communications that could be obtained for scrutiny via a Freedom of Information Act request. Secondly, she was lazy and arrogant, and didn't think she should be subject to the rigors of security the way the rest of us are.
But on a different level, we all knew she felt this way: Reading Gary Aldrich's excellent book "Unlimited Access" where he described in excruciating detail the attitude the Clintons and their associates had about security, from absolute top to absolute bottom, was abysmal to the point of traitorous.
They WANTED to flout security, and they WANTED security to fail. Security was part of "The Man".
Remember the Secretary of Energy, Hazel O’Leary, and her comments about declassifying as much as she could before anyone could stop her?
Part of why they couldn’t prosecute the Chinese spy in Los Alamos: the SoE has already posted it on the internet.
...And the hundreds of people given full access in the Whit House without even having applied for a clearance.
Also, it’s a way of SELLING STATE SECRETS without getting her hands dirty. WHY did all that money flow into the Clinton Crime Family Slush Fund?? So many countries paid MILLIONS....WHY the HELL didn’t they do it themselves??
