Ah, unpredictability. Go through the scanner, and we won't grope you, unless we will.
We get it, TSA. To keep terrorists uncertain and anxious, you're going to keep the rest of us uncertain and anxious. You're going to touch us in new ways, but you won't tell us where or how. So stop talking about "educating," "communicating," and "partnering" with us. You aren't communicating. You're concealing. You want to surprise us. In return, you can expect us to react the way you'd react to an unexpected groping.
I understand your objectives. You want to be unpredictable. And sometimes, you need to pat people down. But combining these two things, in the form of surprise molestation, is a really bad idea. It's a recipe for trauma and confrontation.
Tell us what you're going to do so we can brace ourselves for it. Or maybe we'll choose not to fly. We can't make an informed decision unless you level with us. You owe us that much. This is America.
