Message From: Antigone Davis [/O=THEFACEBOOK/OU=EXTERNAL (FYDIBOHF25SPDLT)/CN=RECIPIENTS/CN Sent: 2/12/2019 7:27:39 PM To: Antigone Davis @fb.com]; Andrea Saul @fb.com] Subject: Message summary [{"otherUserFbid":100019354778553, "threadFbid":null}] Andrea Saul Nosbusch (2/12/2019 10:12:26 PST): >Hi Antigone! I'm going to start putting some thoughts together re: planning for encryption. While obviously real-world harm is the biggest risk, from a reputational standpoint, would you agree with these risks? Anything I'm missing? Andrea Saul Nosbusch (2/12/2019 10:12:28 PST): >1. CSER removal numbers will drastically go down, especially for CT and CEI >2. Referrals to LE will drastically decrease, especially for CT, CEI and grooming > 1. For CT: 98% of our proactive LE referrals depend on Messenger content > > >3. Our ability to comply with LE requests will drastically decrease across the board. This is higher risk for CT, CEI and grooming as well as other potential criminal cases >4. Groups like ISIS view this messaging system as the most useful for their core operation. Groomers have unfettered access to young people. Antigone Deborah Davis (2/12/2019 10:38:16 PST): >These may be captured within what you have: Antigone Deborah Davis (2/12/2019 10:38:58 PST): >NCMEC reports will drop dramatically, these are reported to Congress, there will be policymaker follow up. Antigone Deborah Davis (2/12/2019 10:39:29 PST): >The quality and value of our reports to NCMEC will drop dramatically, rendering them close to useless. Antigone Deborah Davis (2/12/2019 10:41:53 PST): >FB allows pedophiles to find eachother and kids via social graph with easy transition to Messenger. WA does not make it easy to make social connections, meaning making Messenger e2ee will be far, far worse than anything we have seen/gotten a glimpse of on WA. Antigone Deborah Davis (2/12/2019 10:49:11 PST): >Our safety organizations and experts, especially NCMEC and Thorn, have helped us manage so many policymaker and press fires. I know there is this sense that they haven't been there for us but they have helped shorten our fires. (think NCII fire) and they have helped us land and defend things like Messenger Kids. We will lose them. They will abandon us and they will speak out against us. What we gain on the side of privacy we will lose on the side of safety. Honestly, what I'd love is if we did some hard core research to understand what we need to deliver on the privacy side to get our reputation back -- maybe there are other things we could do, most people don't even understand e2ee. Let's understand what they really want :) Antigone Deborah Davis (2/12/2019 10:49:58 PST): >On the diminished value of the NCMEC reports, this will hurt our rel with LE and NCMEC's rel with LE. Andrea Saul Nosbusch (2/12/2019 10:54:32 PST): >Thank you so much. And yes, to sum up, this is going to suck. Antigone Deborah Davis (2/12/2019 11:24:59 PST): >We will mange because we have to; maybe we will even find brilliant integrity solutions :) Andrea Saul Nosbusch (2/12/2019 11:27:39 PST): >Thats what I'm hoping for!
