If you say so :-)
I've been a member of one or more international technical standards bodies for most of the last decade, which requires frequent travel (every 4 or 5 weeks). Roughly 90% of the trips I take are to the U.S., since the standards bodies tend to meet mostly in the U.S., with occasional concessions to non-U.S. participants. So I've built up a "profile" of "normal" behaviour of U.S. customs and imigration--I have a good intuitive feel for when their behaviour is a few sigma away from the "norm". On this occasion, I was badgered repeatedly over the fact that I had a lot of U.S. stamps in my passport, which according to the customs agent meant that I was working illegally in the U.S., and all she had to do was badger me until I admitted it, or lost my cool and became belligerent-- either way she could deny entry. I calmy stuck to my (utterly true) story, over, and over and over again. She eventually let me go, but I suspect that I was within epsilon of getting bumped to "higher interrogation authority". No, they didn't strip search me or do a body-cavity search, but the behaviour of the agent was far enough away from "normal" that I categorize it as harrassment.
