You don't. For obvious reason the state has no interest in opening such a case. The guilty is not going to pursue it. As time passes, evidence and witnesses disappears and often there is no one who really cares.What you haven't found is a wrongly executed person. You've found people who got death penalties, didn't actually commit the crimes they were convicted of, but committed plenty of others.
You look at your "exonerated" criminals, you get clowns like Rolando Cruz. Been in trouble with the law before, have been in trouble since.
How does one find "a wrongly executed person"?
With a shovel or backhoe?
Iran and China do it your way. Shotgun effect. Go ahead and execute folks. They are probably guilty.
I think one of the strongest arguments against the death penalty is the cost. The death penalty is much more expensive than life without parole because the Constitution requires a long and complex judicial process for capital cases. For example: California could save $1 billion over five years by replacing the death penalty with permanent imprisonment. In New Jersey, which halted executions in 2007, a commission found that switching a single condemned inmateÂ’s sentence to life without parole would save the state $1.3 million in incarceration costs alone, because death-row inmates receive special housing and security.
