Not being happy with the status-quo I researched two SCOTUS decisions and learned that border patrol is allowed to stop and briefly question people in order to determine their citizenship.
(They are allowed to question you, but you are not required to answer ...as that would be a 5th amendment violation)
So I developed this script:
Whatever initial question the officer asks me,
I reply in a respectful tone:
"Officer, I am a citizen of the united states and I'd like to go on my way now-am I free to go?"
Breaking down why it works:
"I am a citizen of the united states." This fulfills the citizenship objective of the stop & establishes my ability to invoke the law to my benefit...aka constitutionally protected rights.
