On Thursday, Chicago prosecutors dropped yet another murder charge against an individual on death row on the grounds that another person belatedly confessed to the crime. Although not exonerated of murdering several other victims, this individual — who supposedly confessed to all the killings, even though he has a very low IQ — now must be retried on all counts and may yet be vindicated.

Ironically, two Illinois state senators recently introduced a bill that would allow judges to consider a convicted murderer’s mental capacity as a mitigating factor when determining whether to impose the death penalty.
