I think that’s a habit though – lots of professions have a strictly defined vocabulary so that there can’t be any of the usual misunderstandings and implications we get in everyday speech.
I REALLY would like to know how many commies/morally turpituded (I know it’s not a word)/war criminals they catch this way
As previously discussed at length, it’s not that they are trying to get you to confess, or that this is actually an effort to screen war criminals; it’s to give a legal get-out clause if they want you out of the country. Convicting someone of war crimes to get them out of the country would be a long costly difficult legal battle, but this way all they need to ‘convict’ you of is lying on the visa waiver form which would be a lot easier, and more difficult to refute.
Hell no.. bad language is not exclusive to the Americans of course, but they have a particular style of making up complex terms for simple words to sound more official and serious.
