Have you noticed that Republican numbers are questioned, but Dem numbers are always stated as fact?
Obama DIDN'T get 200,000 in Berlin, despite the TWO Rock bands , free pizza and Free BEER!
The crowd was closer to 50,000.
And it IS possible to verify the size of the crowd if there are reasonable photos and film footage. You can certainly get a sanity check to give a close estimate using a few simple tools.
A case in point is Berlin - Do you really think that crowd was THREE times the size of the crowd he had at Invesco Field?
Of course not, there was the space or the facilities to accommodate 200,000 on the streets around the Victory Column.
I would think today's high-resolution cameras and computer technology would make it pretty easy to estimate crowds pretty accurately using automated shape recognition. First have the computer scan a photo and mark each person-like object it finds with a dot. Then pick 100 dots at random and determine how many are not individual people and how many individual people were not identified as dots. If the dots were chosen at random, that should give a pretty good clue as to the actual number of people.
