You're assuming that the person who talked to Fox News had current information, and not just the initial information, which was several days out of date.

I think that is probably a bad assumption.

I see on the Yahoo map that the island is a ways off a major interstate "5". If they were straight, or up to no good, should be easily determined - that is, their travel story should be easy to determine due to the remoteness of the location. I assume they weren't working commercially since they had a rental truck.

Of course, they could be up to no good unrelated to terrorism, like smuggling.

Score one for you, DG :)
I think that's a valid point.
