Obtaining passwords? Just how do you propose they are obtaining passwords?
Personally I don't believe they should be obtaining passwords by any means. I don't know why you think I want them to obtain passwords.
According to WH Admin, "they" (as in ICE) are obtaining passwords by refusing to allow travelers to continue on their trips until they give up their passwords. While this wouldn't work with me (I'd just say OK, I'll go back home then), I suspect many travelers aren't able to do this.
(And the "I'll just go home then" thing might not actually work. When I was at Baltimore airport waiting for my flight home to Toronto, a group of American border patrol agents approached us and demanded that all the Canadians in the group give up our fingerprints. When I asked "What happens if I don't give you my fingerprints?" one agent glared at me menacingly and shouted "We'll just hold you in one of our detention facilities until you change your mind!" This happened in 2004, and people say things are worse now? Almost unimaginable, that.)
