Don't forget that security checkpoints extend far beyond airports and the TSA these days. Many government or public buildings, museums, schools, hospitals or large office buildings may well subject those entering to all the rigors of a full body scan, wanding, pat-down, dog sniff, questioning, etc.
Do expect to encounter lesser standards for training and professionalism at these checkpoints when compared to airport TSA procedures. At least, they will be different.
My air passenger mileage in recent years has been nil. I'm more inclined to go by car or train, being just smug enough to NOT feel the need for expedited transit in the skies. Also, a greater amount of privacy is afforded me while moving about via surface transportation. I'll even use sleeping car accommodations on a train at added cost to have more access to my privacy when needed.
But ---
I must point out a few experiences in Washington, D.C. a few years ago while exploring the Smithsonian Museum complex. I encountered manned security checkpoints at public building entry points nearly everywhere. It was really impossible for me to arrive at each entry throughout the day while wearing dry protection each time. Quite a bit different from an airport where there would be restrooms before and after a security checkpoint.
During my stay in the area, I'd leave my hotel early in the morning and carry supplies for the entire day, all the while protected by an Abena + booster + waterproof pants. I got 'detected' entering the Smithsonian and pulled aside often. Yes, I was wet; the only places to change were inside. I did learn to explain my condition in more general 'street' terms to the security people. Some did not know what 'incontinent' meant -- too clinical. A more simple (graphic?) explanation came into play for a universal level of understanding -- something like this: "I can't control my pee and I need to wear adult diapers all the time. I see the doctor about it every few months, etc..." Simple, basic. It is what is, take it or leave it. I was cleared to pass in each time, following the few moments of embarrassment in order to reveal my condition to the museum security person(s)in ways they 'got it'.
I even carried a letter from my doctor explaining this, though his expressions might have been too clinical for easy explanation. I never resorted to showing that letter.
Security today is pervasive and extends far afield of airports. I'd even expect it if pulled over by police for traffic situations.
Just wanted to point out a few of the more unanticipated 'security' invasions of our body space that we might encounter in year 2017 and beyond. Think ahead and don't be taken by surprise.
