Which leads me to an important aside: how much of the outrage being vented here comes from people who don't even know that these are two different programs? Take everything you read here with a huge block of salt.
Edward Snowden's rationale for leaking this info is that people never realized that collection of metadata of phone records and PRISM and other programs had gone so far. Maybe SCOTUS ruled on some of this, but the public never realized the implications, largely because it's all protected by top secret classification.
I used the Verizon story in my comment because those implicated in PRISM said in their carefully crafted PR messages that their warrants were for specific subjects and unlike Verizon's vast dragnet. Anyhow, as other have pointed out, it's not hard to draft a specific warrant for the narrow group of 'every US user 13 years or older' which is what I'd presume PRISM involved. Also, the slides leaked for the PRISM stories showed that PRISM was the improvement on older collection techniques of essentially splicing Internet backbone cables.
Agreed on taking replies here with a grain of salt.
Again, though...that program is legal. It's not even a controversial point (unlike with PRISM). From what I know of it, the rationale for the supreme court decision that says mass collection of metadata is legal is fairly well established, has a long judicial precedent, etc.
Yes, Snowden's rationale seems to be forthright. He's bothered by the implications of surveillance on this kind of scale. And I get it -- hell, I even agree. But most of the commentary I've been seeing on HN is just embarrassingly uninformed (or misinformed).
"it's not hard to draft a specific warrant for the narrow group of 'every US user 13 years or older' which is what I'd presume PRISM involved."
All of the public information about PRISM has explicitly said that information can only be obtained when one party to the conversation is a foreign national. I've read nothing to suggest that broad warrants of the sort you describe are any more legal than before.
Granted, IANAL, but I have worked as an engineer in In-Q-Tel funded companies, text analysis, and search. Nothing I'm saying is any reflection or representation of anyone I've worked for and is only my ill-informed, zany, personal opinion.
Can you really get a warrant that broad? I assumed PRISM still entailed warrants issued on a user-by-user basis.
