Imagine what one could do with access to every phone conversation in terms of training a neural network. A properly trained network could easily identify code words among a network of certain individuals and then use the frequency of usage to identify potential windows of opportunity even if they didn't specify time windows over the phone. And do all of this without actually saving a single thing so it wouldn't be considered "collecting".
