I'm not exactly "radical" but my only beef with the death penalty is the fact that too many people who committed no crime at all are wrongfully convicted and sent to their deaths because of incompetent and corrupt prosecutorial malfeasance.
If I could see proof that we're more accurate in all death penalty cases, I don't think I'd have a problem with it at all. I'd like to see one hundred percent accuracy but I know that's entirely unrealistic. I also know that doing more to allow exculpatory and exonerating evidence would probably boost the accuracy a great deal. States are generally reluctant and it takes a herculean effort to get exonerating evidence looked at by the courts once a conviction is obtained.
I support efforts like
"The Innocence Project" because they get results. The Innocence Project claims that as many as five percent of all convictions are erroneous.
So, I'm not against the death penalty entirely. It's just that I support a moratorium on it until state prosecutors start doing a better job.
