I see this desire raised a lot, in contexts from HN to Valley-mocking pieces on how encryption is no substitute for advocacy. I completely understand the instinct, but every incarnation of it seems to struggle with the same question. Namely: how do you know when you've won?
Restrictions against collecting data on US citizens didn't produce the expected results. Testimony to Congress didn't accurately depict what's collected, even in secret. In the early days, the existence of these agencies was classified to help go around restrictions on existing agencies. Years ago, back in the Puzzle Palace days, the DoJ cited systematic criminality but concluded that they were unable to prosecute it.
So... what does winning look like? What regulation, what testimony, what promise could possibly convince people that a solution had been reached, even for the moment?
