I just wanted to point out that it is not just Barr. Various LEOs pine for a way to get a legal way to just 'press a button to decrypt'. Comey advocated for it. So did Holder. So yeah, it did not happen yet, but given the steady push, eventually, it will. It is only a matter of time.

As to the terrorist score, you are right. That would be too simple to target.

Instead, we have amalgam of various private entities collecting information and selling it to highest bidder. At best, the score is distributed.
