What gives us pause is when people are moving in and out of a region.
First of all, it's moving, say, from an airport in Erbil up to a processing centre in Dohuk, for example. The move on the road is, first of all, a dangerous move. People start noticing a pattern of vehicles moving back and forth at regular intervals. People staying in what we call static locations, who are in the same place for long periods of time to do processing of applications, are also of concern, because you have a lot of people arriving at a destination. They stay put. At the end of so many hours, they leave. That gets watched and monitored. That's where we actually are nervous.
As our colleagues were saying, it's all a collaborative effort of collecting the information. If they hear stuff, if they observe stuff, that will be passed on through the various chains of command to make sure their people on the ground are aware that people are watching, or to make sure they adjust their movement protocols or make adjustments to their actual security defence posture.
