One thing would be a near-certainty SolemenI wouldn’t have a cell phone on him or near him. The NSA has shown that if you carry one they know where you are.
All three factors that I mentioned are individually possible. Taken together, they are unlikely. Since each carries a possibility of less than 50%. In the case of a pre-arranged understanding as to WHAT actions the US would take beforehand? Far, far less than 50%.
Man, once they find you, they don’t need to track your cell phone any more, there are other, far more efficient and accurate ways of keeping track of where people/targets are than by pings on cell towers and hot zones. Just sayin.
