I disagree. In the end, all encryption is breakable with a rubber hose. Nothing stops people in a position of great power from abusing that power except social and political pressures. The key is to create a social and political environment that stigmatizes these behaviors.

Unfortunately, we're not there in the US yet. I believe it will come, in the same way that the search warrant became necessary for tapping someone's phone, say, but it will take time for society to catch up.
