I am about 75% - 25% in favor. But the evidence of guilt has to be rock solid.
If an ambitious prosecuter, like the guy who somehow is still in office in Ada Oklahoma, is running the prosecution, no, not even if the perp pleads guilty. Which is the problem with implementing the death penalty. Certain states abuse the law way too much to allow it, so I can easily see the arguement for not using the death penalty at all.
FYI, the prosecutor in Ada, I think his name is Anderson, is <simply put> a son of a bitch. He has railroaded convictions based on "dream" testimony, where prisoners have been forced to talk about their dreams, especially if it involves violent dreams and based on this, he has convinced an equally devil-worshipping judge to get convictions and death penalties using these "guilty" pleas. He once got a life sentence for a guy who a year earlier had hung out with another guy who was railroaded into a death sentence by this prosecutor. Eleven years later, DNA evidence exonerated both of these men. The Real killer pleaded guilty based on one, and only one, deal he made with the police. That he would NOT be tried for the crime in Ada.
As long as there are prosecutore like this one, we should shelve the death penalty for only the most obvious and vicious crimes.
Oh, and one other thing. Ever since DNA evidence has been introduced, earlier convictions in the States of Texas and Oklahoma have been overturned at an alarming rate. Makes you wonder how many innocent people have been murdered for crimes they did not commit in those two states alone. DNA has also proven another interesting fact. Most violent murders in this country have been perpetrated by a relatively small number of people, not the larger numbers that crowd our prisons.
