The hikers

"QUESTION: Back on the hikers, do you have any reason to believe that they did not voluntarily cross the border?
MR. CROWLEY: Again, we’re doing everything in our power to try to figure out what happened, and I would not feel comfortable at this point saying that we have definitive answers yet.
QUESTION: Well, I’m just bringing this up because this is the second time in a couple months that Americans, plural, have strayed into the territory of "axis of evil" members. Are you at all concerned that there’s something going on here, there’s some kind of a trend? Perhaps, does there need to be kind of a special notation in people’s passports now warning them to stay away from sensitive border areas?
MR. CROWLEY: Look, at this point in time, we have three Americans, they’re missing. We’re concerned about them, as we would be any Americans in these circumstances, working hard to try to ascertain what happened, and most importantly, to get them back as quickly as possible."
