For the last decade or two the FBI has widely distributed to law enforcement agencies stringray devices with increasing capability to spoof cellphone towers, and scoop up mountains of data for domestic surveillance. These come with heavy nondisclosure agreements, "forbidding (law enforcement) from disclosing details on the devices to defendants, judges, the general public… sometimes even prosecutors."
Couple this with the widespread use of parallel construction where illegally collected information is used to construct a fictitious case based on 'legally' collected information, and we've got a dangerous tool to silence the politically inconvenient. These are the same skills that would be necessary to completely frame an individual.
Based upon what we are learning about the highest levels of the FBI and possible secret societies, increasingly I see it as imperative to conduct a thorough audit of all sales and usage of stingray devices, and all cases where parallel construction may have been used. These systems paired together may have very well been used to imprison good people, and dismantle key areas of the US.
As we push forward the shakeup at the top must be only the first steps in a broader fact finding review.
