In other words, the TSO might give a more thorough pat-down to someone he/she perceives as opting out in order to send a message or cause trouble, and just a cursory pat-down to someone who is perceived to have a legitimate reason in their eyes.
Either statement should be fine, but it is sad that their own SOP language is considered potentially confrontational. It says I have the right to opt out. I should be able to say that without recourse.
Either statement should also be followed by "and I will need to move to a position where I can watch my belongings." And then do so. Whatever you say, it should be stated in a businesslike manner, even-toned and said with confidence that comes from a proper knowledge of the situation.
