O dear.........public whippings, are we not digressing here to pre enlightenment ethics on punishment. How about the percentage of people who are convicted who are innocent and then they recieve the punishement? What if it is you?
The death penalty does not decrease crime rights neither would publically whipping people like they did in the 15th century, crime still existed.
Our criminal justice system is far from perfect, prison does not always solve the problem and I believe they often harbour and increase criminal activity. However, I do not know the formula to create a crime free society, but punishing people by violence has never worked and it never will.
