And the red square is federal property that is the jurisdiction of federal officers. Protestors broke into and set fire to the adjacent courthouse, in addition to vandalizing and looting nearby buildings, so federal officers were sent to defend the federal courthouse.

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.
