What do you expect from them? Unless saxenaabhi is code for "US CBP Commissioner" or some position of an equivalent power, there is very little that an HN user can do about it at this point.
I'm not an American, but I'm doubtful there's 100 millions Americans out there who think this is wrong, let alone to an extent where they would be willing to do anything about it. If you look at it in terms of scenarios that can actually happen, the US has already decided about a year ago - now they and the rest of the world are along for the ride. Something truly momentous would have to happen now for an agency as powerful as the CBP to change course, barring an unlikely sudden mood change from up top.
> A few things that's happened to me as a citizen after invoking right to remain silent to CBP
What happened that caused you to “invoke your right to remain silent”? When you enter a country, including the US, you are asked some pretty standard questions that would be weird to refuse to answer.
I answered the questions on what I had to declare and anything regarding my identity and citizenship, along with presenting my passport. I also will answer the question to which countries I've been to, although I know of no requirement to do so. I will answer the question about whether I have currency and instruments exceeding $10,000. Other than that I will not answer, nor am I aware of any requirement to do so.
This caused me to be fucked with mercilessly for about 10 years. Eventually I was investigated by an HSI officer who seems to have determined I'm just a crazy libertarian or something, now I tend not to get held up terribly long.
Edit:
I have tried to answer below questions but it appears I cannot post any more messages until a certain times elapses. Below commenter has repeatedly shifted his attack, it is clear only goal is to shift and attack my message through a series of moving questions that keep moving the goalposts. 'This' did not happen 10 years ago, some of the events happened 10 years ago, some of them significantly more recent, and I have pretty much fully defined what sort of questions were answered. But of course it's pointless to even reply such commenters as I know from experience they are only going to dig endlessly until a magic 'gotcha' is found as to why I deserve it.
My sympathies are with you!
