Napolitano's decision was probably one of those that sounded good in theory until people found out about it.
If I was a professor I'd want to work somewhere where I feel safe and secure because it's eerie having someone standing over your shoulders, let alone 24/7.
You mentioned intellectual freedom which is a feeling of security. I find that feeling misleading in the US with the NSA's new data center in Utah collecting our information.
Still it would be wise of Napolitano to reverse course but I think it's unlikely given her background.
