Let's hear how this targeting of engineers from specific European telecoms firms could somehow be an anti-terror measure!?
Open question whether their ultimate targets are terrorists or "everybody."
They're probably officially doing it now to major players, and "rogue" analysts are probably very occasionally doing it to minors for personal gain.
EDIT: It seems like the NSA would be a HIPPA violation by its very nature.
The MO seems to be "go via anything important to get data on everyone to find the terrorists". Where "terrorists" means anything that you want it to.
