There are no hundreds. A handful at best, over how many years? I have no problem with the death penalty. I don't agree with how it is applied, but not for the liberal fantasy that it is applied unequally based on race and socioeconomic position.
What you leave out is a higher percentage of criminals are ethnic minorities, and ALL are poor or they wouldn't need to be criminials, now would they?
I don't agree with sentencing someone to death based on circumstantial evidence only, or the word of one eyewitness. IMO, there should be no shadow of doubt as to guilt. Otherwise, they should get life.
