good points regarding the Canadian. For the Germans: I don't believe that the statements from the ministry are indicative of the three individual cases. Regarding one case, I read in an interview with him that he was detained because his English was poor: He said he "lived" in the USA when he actually meant to say he was just visiting there. That was enough to incarcerate him. Sure, he probably came across as a bit sketchy anyway because his fiancée is American and they have a long-distance relationship, but those are not valid reasons to treat him like that.
