I'm no way trying to defend his agency's actions on encryption - it's chilling and probably one of the most important and defining issues of the information age. Only adding this to point out that people are complex and not black and white and their motives and beliefs and actions can sometimes be in conflict and cognitively dissonant.

With people like this, I'd just really like to get them alone in a room, off the record, and probe their beliefs, motivations, why they did things, etc.
I wonder what it was like to work with Comey at Bridgewater Associates.
