When driving across the border, you're already on US territory by the time you get interviewed by the American border guards. As a result, US law applies and I suspect that you'd have very little recourse if they decided to confiscate your property on whatever BS suspicion they wanted.
What about when doing the US pre-clearance in a Canadian airport? Suppose you don't like the questions they're asking you at the immigration or security stations...do you have the right to simply say, "screw you...I'll just stay in Canada" ??
Just wondering.
