I will to do what I can to help the police catch scammers and crooks who want to steal from people. The police might use those same tools and techniques to help catch people who use bitcoin to pay for drugs; I can't stop them from doing that.
Maybe it's too Libertarian Hipster of me, but man, I don't like the idea of giving succor to the guy with the stick.
Why help law enforcement when you could help the community do its own policing?
I would rather the market solve this, than the BTC community have its own Jose Guerena.
