Bronson,  you are very correct.  A National Guardsman can 'GO' to any protest.  In fact...I would argue that they can also do so 'IN' uniform (I personally dont like this but this their right).  But the minute they speak to a camera or microphone while 'IN' that uniform...they instantly are in violation of the DoD directive and UCMJ which Nat Guard IS held to by LAW just like active and reserve component.  Once they open their mouth to media in favor of the issues of the protest - they are doing a disservice to the neutral position of our National Guard, and active/reserve military service's position.  We in uniform (Guard, Reserve and active) MUST be above partiality.  Tulsi's Congressional position does not put her above the law that she is a member of the same armed forces that I am.   We have seen what happens when someone considers themselves above the law...they lose the confidence of the American people and consequently rightfully a presidential election.
