Why not live in literal glass houses? After all walls and doors can hide child abuse behind them. Why not have a government agent appointed to watch each family? At what point do we accept that the total elimination of a crime is not a goal compatible with a decent life for the other 99.9% of us? Where does this argument end exactly? And how many perverts are using such insecure tools to share their crap? I would (perhaps incorrectly) assume that people engaging in a fairly high-risk crime wouldn't use something like iMessage or the Apple Cloud.
