The way to do it is to sue like Gilmore did, not through individual actions; that just isn't going to produce change in this arena. Let the courts work it out.
I won't argue with that. However,
Gilmore's suit would not have happened were it not for an individual action.
The policies need to change, and the courts are the best way to effect those changes.
Until then, what to do about TSA staff who don't follow their existing policies (e.g., SATTSO)? Pretend that the policy is whatever a particular airport security guard says it is?
