Yes.
Tech question for you nerds.
If Brady or someone did all of their texting with Whatsapp is there any way to get those messages other than getting someones phone? Obviously if you text through Verizon or whoever they can retrieve the messages but can they do it via Whatsapp or other encrypted message services (I think iMessage is encrypted to)?
Short answer, no. Long answer, maybe? I'm sure WhatsApp keeps some kind of audit log on their end, but how extensive and for how long, I have no idea. There's also the fact that service providers install software on phones that log basically all activity, but that would be tough to get to and extrapolate anything from.
