I don't think I'd call this visa policy paranoia or hysteria. It is part of a continuing response to what happened on September 11, 2001. Just yesterday CIA
Director Tenet told a congressional committee that such attacks are still possible. I think there is actually some logic to this visa policy change. Yes, people are inconvenienced, but we are inconvenienced any time we go to the airport.
This policy change doesn't bother me nearly as much as the way the BA
flights were handled recently, as well as some other incidents in which people were delayed for hours in "reverse screenings" for reasons that, imo, seemed questionable. But these things have to be done, as Legacyins said, for national security.
I believe that reacting to the terrorist threat must be a constantly evolving discipline. What is being done today may have to be changed tomorrow. TSA
, DHS, and the other agencies charged with protecting us are still in the learning curve on this, and I suspect will remain that way for some time to come. This visa policy is a response to a deadly serious threat. It's a dangerous world out there.
