Three-man Foot Surveillance.
This is the technique for close foot surveillance.
The main advantage of this technique is that it lets you observe the subject from
two sides. It allows certain several choices when the subject turns a corner. See
Figure 2-12.
As in the AB technique, A follows the subject and B follows A.
C normally stays
across the street and just to the rear of the subject.
The ABC technique allows several choices when the subject turns the corner. Assume
A and B are behind the subject and C is across the street when the subject turns
the corner away from C.
A could keep going straight and B would take the A
position. C would move across to the B position. A would stay across the street,
moving as C had done before.
Figure 2-11.
Two-man Foot Surveillance.
Another approach would be for C to move into the A position. A would go across and
take up the C position, while B keeps his own. What if the subject turns left and
crosses the street toward C? C drops back and A continues in the original direction
and becomes C. B moves into the A position, and C becomes B.
Vehicle Surveillance.
The basic procedures used for foot surveillance are also
observed when a vehicle is used. However, using a vehicle requires that more care
be exercised.
Traffic congestion and traffic laws make pursuit more difficult.
The risk of being discovered may be greater.
