In all three cases cited in the article, none of the people detained were breaking any laws. All of them were United States citizens and had valid documentation on them. However, it appears the agents deemed their valid documentation as suspicious, and detained them for hours or even weeks until they could clear them. If any of the cases mentioned in this article lacked documentation, I could perhaps be more understanding. However, even without documentation, I would think such a matter could be resolved in an hour or two, if someone is a US citizen. Not 32 hours and certainly not 23 days.
As soon as the documentation is suspicious then it loses its valid status. They should hold the kids that were trying to cross the national border as long as it takes to find the parents. The word parents isn't even in the article when I CTRL F.
So if someone looks at my valid driver's license or passport and a agent has a "hunch" that it is "suspicious," it is invalidated? That makes zero sense. I remember going to a bank, and they took my valid driver's license. At the time, my state did not require someone to renew for 15 years, so it was an older version. The bank representative then insisted that they could not open an account because it was invalid. After much angst, I finally got them to see that it was indeed valid and they apologized. I'm sure the fact that my skin happens to be a dark complexion had nothing to do with the initial account representative insisting that my license was "invalid."
If this is how American citizens are going to be treated at ports of entry, I better delay any travel plans until the environment becomes better. I wouldn't want another huge hassle, just because some immigration agent has a hunch that I'm really an "illegal" and my valid documents are "fake."
Even you conceded above that this is stepping over the line. If someone has valid documentation that they are a US citizen, they need to be let in, without undue delay and hassle. Not be detained unjustly for 23 days, while the US fucking bureaucracy finally figures out that they made a mistake. Oh, but that is right. The President has made it clear that if you have a dark tone to your skin, and you happen to disagree with current US policy in any way, you need to go "back where you came from." Even if you happen to have been born on US soil.
