There's a gap between what's acceptable to talk about in terms of motivation for the death penalty (removal of the offender for society, full closure for victims/family) and some of the underlying motivations of people who believe in it (punishment, revenge). As a result it's hard to have a conversation when the two sides are ostensibly in agreement, but in reality have a fundamental point of contention. If you can't get everyone on board with 'capital punishment should not be about punishment or revenge', in terms of what they fundamentally believe and not just what they'll openly state, you're not going to be able to make headway. The documentary illustrated that problem very well, I thought.
