Depending on the exact wording of his Facebook, at least he may eventually have some ground for suit after Arpaio gets done with barry.
If the CIC, any CIC, were to issue an illegal or unconstitutional order, a member of the armed forces would not only be within his/her rights to refuse the order, they are actually required to do so.
So, the Face-book post only makes public a standing policy. His mistake was singling out our current CIC. Had he said that he would not follow any illegal orders, no one would care.
Disclaimer: The first step is to present you concerns to the next step up on the chain of command, and absent any clarifications or justifications, refuse the order. Military members also understand that if they misuse this right, they will be making small rocks out of big rocks for a very long time.
Disclaimer Two: I am not a JAG officer, but this is my understanding of how it works based on 2 years of ROTC, 9 years of active duty service, and a stint at Squadron Officers School.
Meanwhile, homos, gangbangers, and illegal aliens are being recruited into the military.
What a maroon! 1A rights are severely restricted once you put on the uniform.
