I hate to defend Kacey, but do you have an example of her spirited defense of a military officer who said mean things about Bush?
First you'd have to find an example of someone on the attack, calling for Military scalps over criticism of the President. Then you might have something in looking for her defense.
The defense generally follows the attack. This is new territory as far as I'm aware.
But to avoid all the tapdancing, let's get people on record for future reference...
Active Duty Criticism of the President... automatic court martial material?
Release of (arguably) 'confidential' information... automatic court martial material?
Seems like we could find some other people to apply these newfound standards to.
That's not to defend the general in this case. He showed poor judgement, and the President was within his rights to remove him. Then again, removal is always within his rights. He is the Commander in Chief. But court martial or stripping of rank would be ridiculous, and fortunately the powers that be understood the difference.
