Became obvious to me when a car ran over our green box a half mile away, and after it was fixed I began getting someone else’s calls. I could call out, but in reality it wasn’t my phone number.
As to the capitol or any other government building, I’m betting someone would have a difficult time finding a green box. I would think all the phone service would go through hardened, and tightly controlled locations, at least until it got to a trunk.
most assuredly, the lines are underground. beneath a manhole with a telco logo on it.
if o'keefe was trying to social engineer his way in to plant a wiretap, given his high profile, he is an idiot/crazy. imho.
