What are the goals of Gang Stalking?
The goal is to isolate the target from all forms of support, so that the target can be
set up in the future for arrest, institutionalisation, or forced suicide. Other goals of this harassment is to
destroy the targets reputation and credibility. Make the
target look crazy or unstable.
Other goals involve sensitizing the target to every day stimuli’s as a form of control, which is used to control targets when they get out of line. Once the target is sensitized, the Citizen Informants have an easier time identifying the Targeted Individual in public.
These programs are designed to make the targets of this harassment vulnerable,
they want to make them destitute. The secondary goals seems to be to
make the target homeless, jobless, give them a breakdown, and the primary goals seems to be to drive the target to forced suicide, just like what they did with some of the targets of Cointelpro. It's a useful way of eliminating perceived enemies of the state.
