Moreover, any safety measure that creates a grouping of people outside of the safety area (that is, a line to get through security) is itself a target.  We are lucky that nobody has yet decided to set off an explosive or take out a weapon at in the TSA at a busy airport line because the large number of people in close proximity would likely result in a large number of casualties.

Indeed. It would be very easy to do. It is only a matter of time before it happens. We have not been subjected to much organized and carefully planned terrorism in the US since 9/11. The "terrorist" incidents in the US have been a few radicalized "free agents" who were not really part of a highly organized terrorist group. The DHS has probably thwarted a few that we don't know about. We have been lucky, but I can't imagine that will last.
