Sending in unidentifiable and unmarked officers who refuse to identify themselves, to take away seemingly randomly selected protestors to undisclosed locations,

Sending in unidentifiable and unmarked officers who refuse to identify themselves, to take away seemingly randomly selected protestors to undisclosed locations, is a clear authoritarian show of force and scare tactic, worthy of a military dictatorship. How will you know whether you're being taken by federal officers or a far-right militia? That is a deliberate tactic, to have people live in fear of an unknown fate at the hands of unknown assailants.
