If you have any arrests in your history, even if you were found innocent or no charges were ever pressed, and even if the record is legally expunged, by signing up for Global Entry and giving them your finger prints, you will forever be selected for additional screening (bodily and luggage search) every time you go through border control for any reason and in any line. It is NOT easier if you have any history whatsoever, innocent or otherwise. This is not made clear before the application process, and there is no way to undo it. There is no point to legally expunging an arrest record if everyone sees it and treats you like a criminal, even when you are innocent. This has happened to a family member of mine who was arrested as a teen 20 years ago, with an expunged record. The basis of the American legal system is that if you are found not guilty, then you are innocent. If no one ever presses charges, then you are innocent. And, if a record is sealed at great personal expense, then it is not able to create problems for life. The global entry was a colossal waste of time and money, and much worse, a huge violation of personal freedom.
