Now what about the counter surveillance tip? This one comes directly from the field (No I won’t tell you where!) Look for Busy eyes! It is not a normal phenomenon to have your eyes wandering continuously, checking things out etc. It could easily be a sign of someone who is out of place and or up to something not of a good nature. Now this tip goes both ways, as you should be taking in everything around you, but do it in a manner that utilizes “wide angle” perception. Taking in a wide field and then sorting what is relevant to you, The casually moving or focusing your attention on something or someone in a discrete manner.
Surveillance and Counter surveillance tradecraft skills need constant practice in order for you to become proficient, so get going and don’t become the strange guy staring at everyone!(LOL)
