"You have to take off your shoes at the airport and then let a random person take pictures of you naked before getting on a flight because we need to prove that you're not a terrorist. Remember what happened the last time we didn't do that? You can either submit to us, or we can have another terrorist attack."

It also marks a time in history when people started going back to church in order to find some semblance of an explanation, and the churches like the increased attendance. They've got to keep us scared that the "terrorists" are around every corner, and they have the only solution.
