I heard that they admitted they had embellished their conversation to scare/annoy/whatever because they thought she was looking at them.

I agree with the other posters that in the current climate, that behavior is unacceptable (if it is true) and they should be held responsible, fined and sent back home, wherever that is.

That's one way to weasel out of it....

But IMHO the way the conversation went down isn't perfectly consistent with the playacting theory. For one thing, I think they would have added a little more detail if they were trying to yank her chain.

No, you don't threaten to make American mourn on 9/13 the way it did on 9/11, certainly not if you are representing your faith in muslim dress in Public. It's not only evil and foolish, but if you go around pretending to be a terrorist, guess what...some people might believe you.
Shocking.
