Any state could, easily, do the same poll. I hope they do.
I don't know if this was a poll of all crime victims and their survivors or only death penalty eligible cases, which would, likely, produce the highest support.
Oklahoma City Bombing case and the 9/11 terrorism attacks:
I am aware of 4 murder victim survivors who opposed Timothy McVeigh's execution.
That is 4 out of 1680 (10 times 168 murder victims) (2), or 0.2% opposed to execution.
Way under 5%, which would require 84 death penalty opponents, using my method (2).
9/11 terrorism attacks:
I am aware of 3 of the nearly 30,000 9/11 murder victim's loved ones who opposed either Bin Laden's death or those killed in drone strikes who were connected to 9/11 or who have voiced any opposition to a death penalty for any other 9/11 conspirators.
That is 0.01% opposed.
5% would be 1500. I have only found 3.
Sadly, these two mass murders were so huge, it presented this opportunity to see what developed with a media that is always interested to find and publicize murder victim survivors who oppose the death penalty, specifically, in death penalty eligible cases.
When there are death penalty opponents whose loved ones were murdered in highly publicized cases, the media jumps all over them.
I do my own google search for them, periodically, as well as inquire within the crime victim community.
When I get to 84 and 1500, respectively, I will re calculate. Likely, that will not be necessary.
2) I multiplied every murder victim times 10 to arrive at the number of close loved ones per murder victim.
