It is CBP officer not TSA that did this. I had even worse experience. CBP officer standing near boarding gate during an outbound flight to Seoul stopped us ( family of 3). There were hundreds btw but us, asked all kinds of personal questions and ransacked EVERYTHING we have including stroller, diaper bags. Even made us declare the $300 in cash we had with us & our signatures on a piece of paper. Maybe she felt suspicious because we are 2 young asian american couple ( minority) with a baby. She was so unhappy and upset after not finding any accessive cash, she copied my passport info. When we came back, I was subjected to TSA's SSSS watchlist.
