Since a comment was made in another thread about "security holes" in burner phones, I'm taking it over here, rather than continue the convo there and take that thread off topic. I'll assume the phrase "security hole" means that LE could find me via my burner phone, which was:
Purchased 20+ miles from home, in a chain drug store, a number of years ago. I paid cash, using no discount cards or anything else linked to my real ID. I also purchased a 90 minute card, again paying cash. I went to a pubic library, and activated it there. No ID was required to access the internet, and no personal info was required to activate the phone (just the serial # of the phone itself, and the PIN # from the minutes card). When I add minutes, I again buy the cards anonymously, paying cash, and activate them using the phone itself and the PIN # from the card. The phone is rarely turned on, and almost never from home (assuming, in my most paranoid moments, that each phone has a unique ID of some kind, and that it could be physically located via whatever cell tower I'm connecting through). I only turn it on to use it, and then I'm usually in my car, often moving. Rarely, as I said, from home or at work.
So, in my mind, nothing at all connects my real ID to this particular phone #. Even if the # turned up on someone else's call log, and even if LE were able to determine what tower had been used to place the call, that tower most likely would be miles from any place I frequent. Since the phone is rarely turned on, I see no way that I could be physically located through it either (In a practical sense. I'm not going to presume I know what the NSA is capable of, but I'm talking real world here. I'm not out blowing up buildings. And I'm just not paranoid enough to think the NSA gets involved in busting johns).
Sixtyyearold....if you have expertise in this area, or even a plausible theory on what I'm missing or why I"m wrong, please share it here. (And we all know there's plenty of guys out there who'll buy a burner and then activate it from their home phone or computer, or use their credit card to buy additional time. In those cases, the burner serves no purpose other than to keep the call/text logs off their regular phone and hidden from their SO and avoid unwanted calls/texts. LE could find them in a heartbeat if they wanted to). I would like to know the flaw in my scenario, since many of us do it exactly as I've outlined here, and have for years.
