I'll start and say absolutely, yes. I have advocated publicly and aggressively for basic subscriber information without warrant, to my peril in many instances, but I think it's vital. I think the encryption discussion has not yet fully taken place, and the understanding of the implications for privacy concerns is not well distributed. In other words, people don't have a fair understanding of what we're talking about.
To use my colleague from the FBI's analogy, it used to be that the corner of the room was dark and we were all happy with that because we knew that, say, foreign governments or espionage networks were working in this very clandestine place where we couldn't see. But that darkness has crossed into the lion's share of the room now. Traditional criminality, like terrorism, organized crime, child exploitation, and fraud, is being advanced, supported, and accelerated by the availability of these commercial encryption programs.
It's devastating to counterterrorism investigations, and it's a big challenge.
