It's parallel construction all the way down. Discover via extralegal, point mass-capture in that direction, sniff out and send to 'legal' 702 or 215 databases, hint to FBI/DEA buddies, get normal warrant, and now you've got your criminals!

In that way, killing the 702 or 215 powers really wouldn't do that much, because they can just derive their parallel construction from elsewhere.
