should he be FOOLISH enough to try to shut it down I do believe all hell would most certainly break out.
Obama is taking advantage of the shutdown to determine which Federal employees are willing to follow orders and which are grumbling or resistant (personnel evaluation forms will be issued to supervisors at all involved agencies).
On top of that, this is great opportunity to probe the defenses (read: sensitivity) of the American citizens...i.e. just how compliant are the American citizens and where and who are those who are most resistant to authoritarian rule.
You can bet that a database is being compiled of both Federal employees and citizens indicating who is compliant and who will make trouble
