It doesn't appear to be shaping up as a major issue.
These are all cases where we already have the right guy and the sentence is long overdue.
The uncertainty gives them ammunition. How many executions they will actually succeed in delaying is unknown.
A humane method does not necessarily mean a pain-free method. It doesn't bother me if, in the process of execution, a person feels some pain. ... The idea that a murderer is entitled to a painless death, which relatively few of us are going to have, I don't think is sustainable.
We're not going to torture people, but I don't believe there is a right to a painless execution, and certainly there is no guarantee. In the real world, nothing is 100 percent.
