There's a special team of Sicarios drawn from the DCI & NIS (reporting to a civilian with close proximity to those in power) that targets high profile online/social media activists with the later providing technical support & surveillance of online accounts.
The 2 commanders (team leaders) have a group of officers who only take instructions (passed from the civilian) & reports back to them - creating a parallel system of surveillance & enforcement.
The shadow unit operates outside the normal chain of command with the officers involved insulated from regular oversight, whose actions are neither logged into official records nor subjected to internal police reviews.
