>> I'm free speech and pro-encryption, but I am not sure whether grinning and bearing it is really an effective weapon against terrorist activity, considering its ratcheting effects on public opinion. So, if we don't ban encryption, what are we going to do?

I'm in the same position. It's getting harder to stick to my principals. The way I'm trying to think about it though is this: banning encryption and destroying privacy will not fix terrorism. Governments should be focusing on actual solutions to the root cause. Maybe we should stop blowing up the middle-east. We need to work for stability in those regions. Ban encryption and the terrorists will find another avenue to communicate and we'll lose freedoms for nothing.
