I had a cousin who worked for the Dept. of Homeland Security, who once called another relative and asked them to walk outside and wave up at the sky.
Suffice it to say the technology our guys are using is much better than Google Earth.
However...the technology necessary to give even these level of photos, along with the exact latitude and longitude of each point on it, is something many of our enemies do not have access to.
Kinda like sitting next door with a pair of top notch Bino's
Is that why you no longer have a cousin?
