I listened to the audiobook, so I can't speak to how well cited Viola's facts are, but I thought his use of primary sources flowed beautifully in and out of his analysis. I was surprised that in the end Viola doesn't take a stronger stance on whether the civil liberties vs intel gathering debate as it relates to terrorism, given that he's an expert in the field. I thought it was so clever how he connected big historical events one doesn't usually associate with activists or violent demonstrations of the 1970s -- like how it impacted Watergate and 9/11. It put things in a larger perspective of why the debate matters, because it's still ongoing, and it will always be something we have to tinker with as our needs for security and our willingness to give up privacy ebb and flow.
