You know, I actually do feel that way? There's a reason they put the fourth amendment in the constitution. There are people we as a society want the government to be able to catch, if they do it properly.
That's the thing though - they fucked up. They had this interception treasure trove and were caught with their hands in the cookie jar because they're too afraid of the public to stick to what they're... you know, allowed to do. Their lawyers can explain until they're blue in the face how it's not technically unconstitutional, but too fucking bad, they've lost.
The Fourth Amendment reads:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
Really, I think we all want both. But the TLAs fucked up the "shall not be violated... but upon probable cause [list of conditions]" part, and the "right of the people to be secure" part is more important. So until they can get their shit back in order, yes I agree that it's better for them to lose intercept capabilities. Yes that will probably mean murderers, chlld pornographers, and terrorists going uncaught.
Really, the biggest fuckup the government made was personally pissing off the only people who could hurt them - basically, Apple and Google and the other tremendous technology companies. They really do care about both their user's privacy and their own data security - and complying with lawful government requests to the exact extent required. And they took it personally, having the NSA go around the back door when they were obeying the law on warrants. The EFF can talk until they're blue in the face about encryption and PGP-ing your email and so on, but when full-device and e2e encryption are on by default in new iPhones and Androids, that makes a much bigger difference to many more people. And of course to the TLAs.
