trying to hide or conspicuously turning in the vehicle so as not to look at or
face the subject.
b. One-Vehicle Surveillance. When one vehicle is used for surveillance,
it must remain close enough behind the subject to permit the surveillants to
observe his actions.
However, it should remain far enough behind to escape
When the subject's vehicle turns a corner, the surveillants may
continue to follow. They may, instead, make one of two possible moves to help
break the pattern (see Figure 3-5).
They may continue in the original
direction, cross the intersecting street and make a U-turn; the subject will
take little interest in a vehicle turning into the street behind him.
vehicle would be coming from a direction opposite to that which he was taking
before turning the corner.
An alternate move would be to continue in the
original direction, crossing the intersecting street and continuing around the
block. The subject will not expect to be tailed by a vehicle nearing him from
a frontal direction.
c. Two-Vehicle Surveillance.
This technique employs two vehicles to
follow the subject at different distances on the same street. It is the same
technique as in the "AB" method of foot surveillance (see Figure 3-6). This
technique can be varied by having one vehicle going in the same direction as
the subject on a parallel street.
At the same time the surveillant is
receiving radio-transmitted directions from those directly behind the subject.
This technique is more flexible than the one-vehicle surveillance.
because two vehicles can exchange places from time to time; or, one vehicle can
precede the subject.
If more vehicles and people are available, other
techniques can be planned that are even more flexible.
