If I desire privacy would I buy a Blackphone, or would I buy another more common smartphone which I would then secure?
If you're "picked up" or detained and you have a Blackphone, or someone observes you using your Blackphone I doubt very much it would help your pricacy concerns.
If however you have a seemingly normal phone it might be overlooked and simply using it wouldn't raise suspicion.
My point is that this type of phone is more for the "regular" person who simply doesn't want to be monitored (as much) and not covert agents looking for a secure phone/platform for communication.
