Our culture has devolved
It is ludicrous to assume that if we cannot search all equally, we should search none. Common sense tells us that not everyone is equally a threat. Common sense tells us that we have the ability to “sort” by potential danger.
Common sense does not do this:
Common decency does not subject 3 year olds to such acts. In fact, if this was done in any other context than a government sanctioned bit if idiocy, the TSA agent would be doing the perp walk.
Alas we live in an age of no common sense.
