My objection to the death penalty is based on the idea that this is a democracy, and in a democracy the government is me, and if the government kills somebody then I'm killing somebody.
The death penalty is ineffective as a deterrent, and the appeals process is expensive and cruel to the surviving family members.
Our criminal justice system is fallible. We know it, even though we don't like to admit it. It is fallible despite the best efforts of most within it to do justice. And this fallibility is, at the end of the day, the most compelling, persuasive, and winning argument against a death penalty.
The death penalty issue is obviously a divisive one. But whether one is for or against, you can not deny the basic illogic - if we know the system is flawed, if we know there are innocent people on Death Row, then until the system is reformed, should we not abandon the death penalty to protect those who are innocent?
I submit that an individual who breaks a law that conscience tells him is unjust, and who willingly accepts the penalty of imprisonment in order to arouse the conscience of the community over its injustice, is in reality expressing the highest respect for law.
