So you have a problem with cooperating with the authorities? Is there something illegal or anti-constitutional about the way our border patrol acts? if so we better change the constitution or simply give up and invite the entire world to live here while we pay for it.
I did not say to surrender your 5th amendment rights, But to follow the law and not to be an asshole. I could have refused to answer the simple questions, but why? What exactly does it gain anyone to refuse these simple questions that might help identify an illegal? Is this undue harassment? I don't think so.
I do if they insist on asking people a question after they assert their right to remain silent, just like I do if they insist on taking away the other 9 Amendments in the bill of rights. What if you are driving along a back road in Arizona and come across a ICE checkpoint and they decide to take away your guns because you do not have a carry permit, which you are not required to have in that state. Would you have a problem with that, or would you insist that you have a constitutional right to keep, and bear, arms? Would you simply drive off after they take your weapons because they are just doing there job and you don't want to be an asshole?
That guy was not an asshole,
and asking a person about citizenship is not legal. The law states that ICE is to assume that anyone they encounter is a US citizen unless they have probable cause to suspect otherwise. You do not have to prove you are a citizen, nor do you have to answer questions about it unless you are actually crossing the border. The only people that are required to answer these types of questions are people that are visiting the US on a visa, and legal, or illegal, aliens. The rest of us can freely ignore ICE if they approach us. If that young man had, as you are implying, been under some sort of legal obligation to prove anything he would not have been released when CHP showed up. In fact, CHP would not have been called at all, because ICE is a law enforcement agency, and is perfectly capable of arresting anyone that breaks any laws.
It is not undue harassment, whatever that means, to ask about a person's citizenship. It is, however, harassment to detain a person for not answering.
