Question

What modern instances does the justice give?

Answer 1

The modern day justice system is quite different from that in the past. Today, a person is not guilty till proven to be or pronounced guilty by a law court. A person pronounced guilty by a lower court has the right to go to a higher one to seek redressal and, therefore, reversal of the original judgement.

Criminal justice procedure in free societies has several systems in operation, viz. Law Enforcement, Prosecution, Defence, the Court System, Corrections. The three major components that ensure criminal justice system is fairly and properly run are the Police, Courts and Corrections.

Unlike in the past, another change has come in the virtual disbanding of capital punishment or death penalty. In the rarest of rare cases, like heinous criminal activity or treason, is capital punishment pronounced by the law courts. Even after it is pronounced, free societies have a provision in place by which the guilty can seek presidential pardon; if the appeal is upheld, then death penalty is converted into life imprisonment. 

Answer 2

Modern instances of the justice have changed over the period of time the people are not held responsible for something they have done until they are proved guilty by the court or police. And after the person is held responsible for something he has done and there is a death penalty for them they can still appeal and get their death penalty converted into life imprisonment. 
In the earlier days, people were punished there and then and they could not even appeal that they are guilty and their punished should be minimized a little bit.
