"We are not supposed to go out and kill all those we suspect to have committed a crime"

In this quote, Bianca Jagger is stressing that people are not enabled to take the law into their own hands and serve as judge, jury, and executioner. It is not the duty of the public to recognize and penalize those who may have devoted a criminal activity, but rather the obligation of the legal system. Vigilantism is not excused, and violence ought to not be used as a means of seeking justice. Instead, we should rely on the guideline of law and due process to guarantee that justice is served. Jagger is advising us that taking the law into our own hands can cause turmoil and a breakdown of society.
