Various reasons
Some people think they're "informing" the public of a "threat" (which of course exists mostly in the mind of Farah)

Still some want it to happen so they can blame it on President Bush (which is IMHO what Farah is really hoping for)
""Still some want it to happen so they can blame it on President Bush""
I think youre right. I also think they want it to happen via Mexico, so we will deport all the illegals
