Corollary: if you want justice, deduct the mob, and the threat of the mob. In a sane society eliminating the threat of terrorism would be the job of law enforcement.
How we eliminate what might be called social terrorism, or Leftist McCarthyism (McCarthy was not a good person, but also not wrong, or as abusive as the image created by Leftist historians, but if the word was given power, lets use it) is another question.
Mob behavior should be called Bloodlust, or perhaps Mob Vampirism.
