If the elected legislative branch doesn't dictate these rules, the unelected judicial branch will. Is that really what you want? I don't see that as an improvement, and I don't see any way to avoid having courts fill the vacuum.
I really want the airlines, not the government, to choose security procedures. That way, I can choose which airline(s) I want to fly based upon who offers the best security with the least harassment.
The government should not be permitted to interfere with this competition.
