Final answer:
Illinois has the most death row inmate exonerations according to the Death Penalty Information Center, even though states like Texas lead in executions and California has the largest death row population.
Step-by-step explanation:
According to the Death Penalty Information Center, the state that has had the most death row inmates exonerated from possible executions is Illinois. Despite states like Texas having a high number of executions and California having the largest death row population, it is Illinois that has seen a significant number of exonerations. DNA evidence has played a crucial role in reviewing past cases, revealing instances where individuals were wrongfully executed, such as the case of Claude Jones in Texas. This has contributed to a shift in public opinion against the death penalty in some areas and the abolishment of capital punishment in several states.
