Nothing can actually legitimize those tactics, not legally, morally, ethically or constitutionally. But I get your point. They will take it as validation because it worked. And by worked I mean suppressed real opposition and enacted retribution on those that dared to think they could change the power structure. Only power matters. If 2020-22 has taught us nothing, it should have taught us there is NO extreme too great to suppress the outsiders and real opposition to retain and expand power.
