What good does blurring the US Capitol do?

Someone thinks they can hide the location of the US Capitol! If you go to maps.google.com and type in 1600 Pennsylvania Ave. Washington DC, and click “Satellite” in the top right corner, follow The Mall eastward to the Capitol, the Capitol building appears blurry when everything else around it appears clear. [Mirror]

Also the White House looks flatter than the other buildings around it that have a shadow. Any ideas why someone would want to try to hide the location of the Capitol?
