Question 1: Types of Informers, Their Motives, and Ensuring Their Safety
Informers are a critical source of intelligence in criminal investigations. They occupy
a unique position within the law enforcement information-gathering process because
they operate from within communities, social networks, and sometimes even crim-
inal organisations, providing information that investigators could not readily obtain
through formal channels.1 In the Carltonville case study, three informers accompa-
nied the two detective constables, illustrating that informers are deployed not merely
to gather background intelligence but also to assist in the active tracking and identifi-
cation of suspects in the field.
1.1 Types of Informers
The literature identifies several distinct types of informers, each defined by the con-
text in which they operate and the nature of the information they provide.
(a) The Voluntary Public Informer
The voluntary public informer is an ordinary member of the community who, without
any personal stake in the matter, comes forward to provide information to the police
out of a sense of civic responsibility.2 This individual typically has incidentally wit-
nessed criminal activity or possesses knowledge about a suspect. In the Carltonville
context, the three informers accompanying the constables did not appear to be act-
ing in this capacity, as their involvement in active field operations goes beyond what
one would expect of a concerned citizen.
