So now NSA is eliminating "about" information in the Upstream database, meaning it's now limited to info to-from selectors of interest. 9/

Now, NSA allows analysts to search the Upstream data the same way they'd search PRISM for USP information, expanding haystack. 10/

But this still doesn't resolve issue that NSA/FBI can now search combined Upstream & PRISM databases w/o a warrant for USP information. 11/

Do FBI is still not supposed to be searching upstream at all. That may (likely to) change w/new changes.

That's what I thought Charlie was reporting in the updated article.

Last I checked it it just referred to NSA searches on upstream. Tho possible violation is getting upstream metadata and using it for PRISM.

So wait,
@charlie_savage does the changing of the Upstream search audience broaden it to FBI, or just NSA looking for USP identifiers?3 replies 0 retweets 0 likes -

Also note: To some degree it doesn't matter, as all upstream about is at least ostensibly intl comms, so available under 12333.

Except a 12333 database searched by NSA, has a different constitutional set than a combined Upstream/PRISM one searched by FBI.

Under the new sharing rules FBI can search that 12333 database now. The biggest diff is AG approval standard actually higher than FISA.

Not necessarily same/full database. I have been led to believe that agencies that get 12333 sharing have to make case for specific streams

That's right. Not all 12333 collected info sits in the same database. Highly segmented.
