Well, I have learned a bit about surveillance from Edward Snowden and William Binney, but...well I just don't really 'get it.'
I do know from William Binney that the supposed purpose for the surveillance, i.e. to screen for terrorists, could have been accomplished much more efficiently than the system ultimately chosen, and without violating our constitutional rights.
But why would China want to know about me traveling through the secluded violet prairies of SW Washington State, taking delight in this year's crop of blue camas? (That's a rhetorical question, not really needing a rational response.)
Here you go, this is fairly close to what I see -- you can see the evergreen Douglas fir in the distance, trying to encroach and take things over.
