Here is a technique of spotting if any agents that are following
you. It is used extensively by the CIA, MI5, the former KGB,
Mossad, and any agents on covert missions. So far there has been no
effective counter measure against this move. The only thing that
can be done is to change the agent that is following the target.
The technique is called "Spotting Your Tail".
When you are walking along, and you suspect that you are being
followed, just continue walking, until you come to a straight
pavement that must be at least 50m long. The pavement must be
blocked on one side, i.e. there must be a blank wall, no openings
such as door way or shops. Preferably the street be clear with no
parked cars. When come to such a pavement walk the length and when
almost at the end, bend over quickly, with out giving any warning,
and look between your legs at the people behind you. All bonafide
pedestrians would look at you, but the agent following you will
instinctively pretend and walk by, whether you spot him or not, he
will assume he has been compromised, and call for a change. This
will take time, and you will have some free time before another
agent takes over.
Simple but effective even against the best.
