Just finished watching all episodes on iPlayer... Turned out not to be a good choice of tv for a night when DH was away since all the crimes seemed to be against lone women.
I think they're brilliant programmes - nuanced and careful to show both sides. The practicalities of how a state goes about killing its prisoners are so strange, and perhaps even more off-putting than the the ethical aspects.
I wondered who sat on the Clemency hearings board? Until the very last prisoner they didn't recommend clemency for anyone - even the ones whose lawyers cried, or where one of the victims asked for clemency.
