Should doctors participate in executions?

Ty Alper interviewed on NPR Weekend Edition, May 4, 2014

“I am opposed to the death penalty, and I don’t think that we should be executing people. But if we are, and particularly if we’re going to do it by way of procedures that are shrouded in secrecy and that use experimental combinations of drugs that have never been used before, then we need to have competent medical personnel involved. And I think that courts should require that qualified, competent medical personnel participate.”
