Dry Runs Another sign to watch for is "dry runs." Before execution of the final operation or plan, a practice session will be run to work out the flaws and unanticipated problems. A dry run may very well be the heart of a planning stage of a terrorist act. If you find someone monitoring a police radio frequency and recording emergency response times, you may very well be observing a "dry run." Another element of this activity could include mapping out routes and determining the timing of traffic lights and flow. This stage is actually our best chance to intercept and stop an attack. Multiple dry runs are normally conducted at or near the target area. Deploying Assets/Getting Into Position The seventh and final sign or signal to look for is someone deploying assets or getting into position. This is a person's last chance to alert authorities before the terrorist act occurs. It is also important to remember that pre-incident indicators may come months or even years apart. It is therefore extremely important to document every fragment of information no matter how insignificant it may appear and forward this information. 124
