It wasn't a "fine". If you exceed the duty free allowance, you owe tax on the goods over that.
Consisten with your spewing this birther type crap which is pretty much a rehash of stuff from a far-right xenophobic blog, you seem to think a wealthy woman traveling without her husband is somehow unusual. They had just finished a campaign and she took a shopping trip.
In the first place, that's not very unusual for a woman to travel without her husband. In the second place, there is no source for the idea she was "alone" in the first place. She was traveling without her husband, which women are allowed to do, so the stories refer to her traveling "solo" - ie without him. However, if she was traveling with friends or social acquaintances, which is highly likely, the odds are they don't want their name in the papers, and it's not as if the only sources for the story - her and him - would name the friends on the trip. As far as customs is concerned, they don't know whether any group of unrelated people are traveling together or not.
Your whole point - that she has lived in the country for decades and speaks no English is bog stupid. Likewise the "forged passport" which hasn't been possible for quite some time. When you enter the country, the passport data is scanned and checked against the database. If you go to secondary inspection at customs, it's not as if that is some "distraction" from the rest of your documents - it gets you extra scrutiny.
Again, this is racist xenophobic bullshit. which is why your other thread was locked. She speaks English with a heavy accent as do a lot of Americans, and you can watch and hear her speaking English in the video I posted above.
