A local judge introduced the concept of the "Three Rs of Justice: Retribution, Restitution and Rehabilitation."
Retribution may involve punishment. Retribution may be a form of vengeance. Do retribution and vengeance make the world a better place? Perhaps they may help people feel better.
Restitution may be financial. It may involve paying back money stolen. Probation may allow the perpetrator to keep working and earning money. If the perpetrator is in prison, repayment may be more difficult.
Rehabilitation seems to be the ultimate goal. How do we encourage people to become good citizens?
Social justice makes the puzzle more interesting. Do all people agree on what is socially "just?"
Restorative justice has been mentioned many times. I will leave an explanation of this to others.
The next time that you hear people demanding "justice," be careful. Try to figure out if we are speaking the same language.
