So, to theorize a bit more about this, I put myself in their shoes. If I entered a country with other Americans on the same flight for the same school in a remote part of the country, and then I went off on my own while others went all kinds of other directions, and I did not ask for the slightest help to get me oriented back to my approved destination, I would be harboring nothing but a nefarious intent.
And that is what each of these 11 young men did.
I doubt they are upstanding young people. And I strongly suspect they had other operational plans, and are part of a terror or testing (dry run) network, being run out of Egypt and in concert with al-Qaeda, or some other radical islamic group.
Absolutely, I agree 100%. There is no excuse for this. None whatsoever.
