Librarians turned snitch?

What is interesting is that there is apparently no concern with warrantless surveillance of any and all electronic communications outside of the United States.

So the legal solution is simple:

We monitor all coversations in Canada and Canada monitor all conversations in the United States. If either country finds something suspicion they let the other intelligence agency know about it and traditional legal investigation can begin (or we could just turn a blind eye when the RCMP launches anti-terrorist missions into the United States to take our suspicion chatters).
