I do agree that the negatives of dragnet surveillance disproportionately harms society - much greater than the net-positives. I just don't feel like we have enough transparency to correctly scale that bar graph.
I fully believe dragnet surveillance is dangerous. My point is, I can't just say "Dragnet surveillance is dangerous." A well-formed argument has citations and metrics and something to show relative scale. The people pushing for dragnet surveillance (those people in positions of authority) feel like they're keeping us safe and doing what needs to be done - and that we just don't understand. We need to KNOW exactly how much surveillance harms us - we cannot argue with blanket statements.
