Mystery: How did DHS get records of a #Google VOIP call using a #DEA database of telco records? https://www.emptywheel.net/2015/04/16/the-government-changed-its-mind-about-how-many-databases-it-had-searched-after-it-shut-down-the-dea-dragnet/ … via @emptywheel
@WilliamOckhamTx So where does that call hit AT&T's switch? @PatrickCToomey @csoghoian

@emptywheel@PatrickCToomey@csoghoian Either as an IP packet or as POTS call, good chance it hit AT&T's network on its way out of U.S. -
@WilliamOckhamTx Does that depend on what kind of call the Iranian was making?@PatrickCToomey@csoghoian -
@emptywheel@PatrickCToomey@csoghoian Lots of variables, but doing deep packet inspection on AT&T lets you launder through dragnet du jour -
@WilliamOckhamTx True, but the whole point is that's not the program either DHS or DEA have described in the case.@emptywheel@csoghoian -
@PatrickCToomey@emptywheel@csoghoian The 'dragnets' describe a 'legal basis' for searching the data, not technical system collecting -
@WilliamOckhamTx and the notion that these are discrete "databases" plays into that, no?@PatrickCToomey@csoghoian -
@emptywheel They are playing Go Fish, but they have already seen your cards. Easy to know what to ask for.@PatrickCToomey@csoghoian -
@WilliamOckhamTx You're saying there aren't distinct interfaces or that they clean up on parallel construction?@PatrickCToomey@csoghoian
