Re: CBP is committed to preserving the civil rights and civil liberties of those
Actually, at all borders non-citizens have very limited rights before entry into any country. As a non-citizen of Canada and the UK, they can put just about any rules they want on me (US citizen) prior to entry and there is very little I can say about it. This is mitigated by treaties and the fact excessive jackassery will provoke a retaliation.
Also, citizens reentering have to declare what they are bringing back and are subject to search if the agent gets suspicious. One time, when I was young, I was go through US customs in JFK and the person immediately before me was nailed for trying to smuggle chocolates into the US. All I had to do was answer a few questions and I was waived through.
