This is really not a good article, and probably not likely to lead to a good discussion, due to the lack of hard information. It's all just speculation by supposedly well connected people on how they might have done it. I don't think it's likely we can have a productive discussion until some more hard information comes out on exactly what happened regarding counter-surveillance tactics actually used. It's just gonna be more speculation and partisan bickering. Hence, I flagged it, and I suggest others do so as well.
