NSA knows everything you do, including what you buy, no matter how you pay, unless it's cash. Including 80% frames. So if they want to, they can track you down and know what you have and get it. This why, for example, in VA, a new law passed that you have to report lost or stolen guns to the police in 72 hrs. The boating accident thing won't work. Location services are always on for the service provider. The switch on your phone is just for commercial purposes. Oh, and you are on this forum and they know that too.
