I understand that US justice system is completely biased against minorities (Mainly blacks) but i can't completely come to terms with total abolition of death penalty as expressed by many here on HN. Here are few incidents where i think death penalty can be justified (examples are from Norway which has abolished death penalty & India where it is very rarely carried out - only 5 from 1995)
