I can, but who says Kirk and Sulu were doing anything of the sort? Kirk come to visit McCoy. If he wasn't supposed to be there, the guards should not have allowed him inside the cell and should instead have asked him to wait until McCoy was moved to the appropriate psychiatric facility.
Sorry, I messed up the quoting. I meant to address the statement that "Kirk and Sulu still held higher ranks than they did. The guards had no business ordering them around anymore than someone serving on another vessel would. [...] Enlisted personnel do not order around flag officers under any circumstances. The guards were out of order."
