> if you're caught making a joke about ISIS, the Whatsapp police can unencrypt your messages

Would you please clarify this? I know that messages flagged by the recipient can be read by moderators [1], but I'm not exactly sure what you're getting at here.

I'm not defending WhatsApp (I've advocated for Signal since the days of TextSecure), but AFAIK the messages are encrypted using the Signal protocol, so I'm not sure how the "WhatsApp police" would be able to determine if you said something specific without the recipient reporting it.
