I find the options in this poll to be odd, since both "support" and "condone" have roughly the same meaning here, and "oppose" is not even an option.
However, moving on. I believe the death penalty has it's place, when the crime is so heinous and guilt so obvious as to remove all doubt. I'm talking serial killers with the bodies of their myriad victims found buried in the basement of the suspects house. That kind of heinous, that kind of obvious.
To my mind the death penalty is used far too often, and is too frequently asked for by prosecutors who either want to advance their own careers and status, or need the death penalty as leverage to coerce defendents to accept a plea bargain. Death row inmates are being exhonorated by DNA evidence. That alone is enough to stand back and say, "waitaminute, innocent people on death row? We're doing something wrong here."
The death penalty is overused, in my opinion, and I do not have a single doubt that innocent people have been executed.
