I do have a problem with the death penalty in such convictions.
What if there was an eyewitness?
"I do have a problem with the death penalty in such convictions."
Why is that? Suppose a murder is committed such as this one and there are 3 or 4 eye witnesses on the scene. Each independently describes the individual down to the scar on his neck or some other such defining physical characteristic. The man is then picked up, has NO alibi and is again ID'd in a line up by the same witnesses. What's wrong with the death sentence in a case like this?
