what would exist in its place? airlines are responsible for carrying their cargo and their passengers. why should we assume that a bureaucracy can do better, and look at the monstrosity we have at the airports. these tsa agents are abusive, they are sometimes they are accused of all kinds of sexual activities on the way they maul people your best at lax tonight you know, i would think the airlines should treat passengers as well as a company that hauls money around, and they protect their money. they have private guards, and they could do it. just remember, 9/11 came about because there was too much government. government was more or less in charge, they told the pilots they couldn t have guns and were told never to resist. they set up the stage for all this, so no, private markets do a good job in protecting, much better than this bureaucracy called the tsa, let me tell you.
