Capital punishment does not work. There is a wealth of mounting evidence that proves this fact.
The death penalty, both in the U.S. and around the world, is discriminatory and is used disproportionately against the poor, minorities and members of racial, ethnic and religious communities. Since humans are fallible, the risk of executing the innocent can never be eliminated.
Furthermore, the astronomical costs associated with putting a person on death row – including criminal investigations, lengthy trials and appeals – are leading many states to re-evaluate and re-consider having this flawed and unjust system on the books.
