The article says, "Federal officers testing a program at Tampa International Airport that selects passengers based on their behavior to use a speedier security lane may expand the program..."

Why can't a program like this be implemented with an "innocent until proven guilty" mindset? That is, let everybody use the speedier security lane by default and select only the "suspicious" ones for the full laptops-out, shoes-off, nude-o-scope, and grope procedure. (Not that I approve of the latter!)

Starting with a "guilty until proven innocent" mindset is not sustainable. If a minority of travelers are selected for the speedier screening, and the selection criteria are not evident, TSA is only going to get complaints about injustice (at best) and lawsuits about profiling (at worst). TSA's credibility in the eyes of the majority of innocent travelers will continue to fall.
