I imagine most who were changed by Snowden leaks are not necessarily trying to be vocal about it.  Instead I figure they&#x27;re just doing something about it.  These are the people who, even if they were part of the &quot;I already knew what was happening&quot; bunch, probably wouldn&#x27;t have done anything about their beliefs since they were only that.  Hunches without enough evidence to warrant digging too deeply about, and certainly not enough concrete data to warrant dedicating one&#x27;s life to.<p>It&#x27;s a far different thing to call out your government and demand something when there&#x27;s no concrete evidence to support your claims in the first place.  Now governments must take citizen demands seriously, and people can now pursue these things without fear they&#x27;re just spinning their wheels, because we&#x27;ve seen real evidence.<p>It&#x27;s these kind of people, the ones who realize it means nothing to talk about something unless you&#x27;re actually going to do something about it, who I&#x27;m talking about.  My belief is leaks like this have the power to change enough people to make a real difference in the future of civilization on Earth.<p>And keep in mind.  I didn&#x27;t mention in my original comment, but Snowden leaks are something that as far as I&#x27;m concerned could warrant being required reading in undergraduate history textbooks (core curriculum).  I think it was the kind of historical event that will continue to affect Earth&#x27;s inhabitants centuries after we&#x27;re all gone.
