If we aren't going to abolish the death penalty, we should at least require a higher standard of proof than beyond a reasonable doubt to carry it out. It should require incontrovertible proof. Circumstantial evidence should not be allowed. Expert testimony should be barred. The evidence must be conclusive, plain, and certain to every member of the jury. This would allow you to execute, e.g., mass shooters who give themselves up, but make it extremely unlikely to irreversibly kill someone on the basis of junk science, induced or extorted testimony, or other fallible evidence.
