i haven't seen this brought up before, but
Stingray type devices** are also used in
extra-judicial "disruption strategies", where a
target's communications are denied and interfered with.

Disruption strategies are to be implemented,
according to the guidance document, when
sufficient evidence is lacking that someone is a
threat; when agents do not have the grounds to
continue an actual investigation according to
internal guidelines; and when there is no way to
bring formal criminal charges against an individual.
...
According to the FBI's own internal guidelines
in Section IV(V), a âDisruption Strategyâ
may be implemented when the investigation has
closed, when the threat is over, and
essentially, when there are no more legal,
investigatory or constitutional means of continuing the investigation.
Disruption, then, seems to be a last resort used
when the FBI's investigations lead to a
dead-end. And it is a strategy to be deployed even when there is no threat.
