Terror: defending or causing?

The Governments are getting paranoid. Proof that they are comes in the form of the deceased Jean Charles de Menezes. Not that I blame them of course but what happened in this recent incident is clearly uncalled for. Now we find that even the chief of police of one of the major cities in the world is lying to us. What's next? Whom do we trust? For it is evident to one and all that the Governments will not protect us individually anymore if only to defend their ill-bred policies.
