Peter - you should absolutely tell the next U.S. border guard that you meet that the system is stupid. After all, it's his system right. Give him some smart ass answers about how you're not staying in his crappy country, because I'm sure nobody has ever told him that before. While you're at it, you should tie some pot leaves to your head and make some fake fuses for your shoes. It will sure lighten up the guards day and he's sure to appreciate your point of view.
I asked that particular immigration official (not a border guard) why the USA did not operate the transit system operated around the world. This was after waiting in line for 5 hours with thousands of other deeply frustrated people, and after having already missed my onward flight. His reply "haven't you heard of 9-11?" made absolutely no sense to me, and as we were clearly destined to share the next few minutes together while he did whatever he had to do I replied that of course I had, but how did that bear on the current problem? I guess he thought I was trivialising 9-11, whereas I simply couldn't (and still can't) see any connection.
For interest, a close friend of mine lost 12 work colleagues in that atrocity, including two I knew personally. I don't joke about things like that.
