Broadcasting the exact usage of Tor exit nodes would be a net loss for privacy. While everyone should be using HTTPS over Tor and treating the exit node as they would a massive public open WiFi spot, not everyone does so. Putting such users at risk publicly exposing accidental usages of HTTP doesn't help. Furthermore, releasing the previous-hop starts to degrade the privacy of Tor, a little bit. That's not a good thing. LE can figure out how to go after "pedophiles and terrorists" using other gumshoe techniques, instead of trying to downgrade everyone's opsec. Not to mention this idea of vigilantism is... a terribly bad idea (to put it politely)? You're actually advocating that people go lynch/kill others based on Internet traffic logs. Nothing's stopping all sorts of sites from embedding links to "bad" content and framing people. Or, exit nodes can just fake the log information if they wanted to.
