There are two separate points there, one about America and London acting inappropriately and introducing too many restrictive laws after terrorist attacks. On those two points I broadly agree and I am under no illusions that America is just as guilty in many cases as the countries they invade. The other points are about you seeing conspiracies in every atrocity. If we accept your theory about governments clamping down on freedom after atrocities, could it not be possible that these bad things just happened independently of any conspiracy (which I believe is what the majority think happened) and that the governments then used these as opportunities?
