Some illegal activities of IC may happen. I consider it acceptable as long as it is really small scale. In order to fight terrorism efficiently, we may need some large scale monitoring of phones (and/ot car movements). These large scale monitoring should be unambigously regulated. The principle of separation of powers (I am french) should apply.
