Easy, criminals can remain uncaught because innocent people are willing to hide them among us, or just do not object to it. If everyone thinks someone is a scumbag deserving some punishment, they will all actively participate in spotting him, like if he tries to use Coinjoin everyone will refuse to mix with his coins, then he has no place to hide.

The law-enforcement could even be compelled to be more transparent, because they have to do so to get our help, rather than forcing it upon us.
