Well i can't actually proove that i'm not a cop. All i can say, is that i'm not. I think you are all too stressed up with this NSA bullshit.
NSA isn't looking for drug users, as far as I know. No offense, but is this app really the smartest idea? Why would anyone want to download incriminating evidence that lists how much plants they have, how they're growing them, etc.? Seems like a great way to streamline your trial. They'll know exactly what to charge you with and how many charges you should get.
