Police Operation on Street View
The Google Street View camera caught a snapshot of a police operation in Prague in Senovážná Street while moving right through the scene. Some images have been replaced by later shots, possibly to conceal a failure or a paranormal phenomenon – see the photos below.

Most images from 2009 showing the operation were replaced with later ones from 2011, which you see when you move up or down the street.
