This is not something that can be or should even need to be "debunked". It is the responsibility of the government to act in a way that engenders trust of the citizens. For example, not deploying roving gangs wearing masks and refusing to identify themselves while purporting to act with government authority. Surely you can see how this destroys the rule of law, regardless of whether those are 30 year career civil servants who just now happen to be wearing masks, or some newly-formed lynch mob.

In general, the government justifying itself to citizens is called leadership. This "government" does the exact opposite across the board, and compensates with divisive propaganda that nurtures loyal all-in extremist followers.
