I was on a MHT-ORD-SFO flight the other day, and I handed the ID checker my MHT-ORD boarding pass. The guy then asked me if ORD was my final destination. When I said no, he began to ask me questions about where I was going. At this point I became beligerant and said I don't know, and I won't know until I get to ORD. That was the end of it until I was "randomly" selected for additional screening by the WTMD... I've never been asked questions like that anywhere else. Is the TSA starting to expand the behavior detection program that was previously limited to BOS?
