It is difficult to prove the innocence after death sentence. There is a possibility that the person who is not guilty would be sentenced to death. We should begin by thinking that the death penalty is not justice. I used the word "innocent" in this poster to show injustice of death penalty. We have to listen to the voice of "I am innocent" behind calling for death.

Death is not justice

Our 2010 project asked for the universal abolition of the death penalty.
For us it’s simple. The death penalty is a violation of human rights.
Article 5 of the Universal Declaration of Human Rights states: “No one
shall be subjected to torture or to cruel, inhuman or degrading
treatment or punishment.”
How does that fit with beheading, stoning, hanging, lethally injecting
or shooting someone?
