So I am guessing I don't have to answer their questions. When answering how did I legally obtain a US passport I answered the same way you probably did.

It's becoming a habbit and an uncomfortable one at that. By the way I assume they are customs agents as they flash a badge. Never really took the time to read the badge and it has only happened on international flights. Only time it happened when going to Europe was to Spain. Whats funny is when I got to spain pass port control stamped my passport quicky, I had a harder time getting into canada than I did spain heck had a harder time getting on to the plane than I did off..
