Are we all just going to take this seriously? It's pretty obviously a fake. Just look at the names at the end. Detective Laughlin Foo? Stu Pitt? Neither of which, incidentally, return anything in google aside from this presentation. There's also a clear divergence in style on the backdoor slides, and it reads like a parody.

But the most obvious problem: if the NSA or whoever had a backdoor to truecrypt and Android and iOS, they would not send that information to a local DA office to be leaked.

Please don't set aside critical thinking just because something confirms your biases.
