I believe that was a twittered number. Please don’t quote DC Police unless it has been officially verified. There will be attempts to dicredit this event with super over inflated numbers in the millions. Then when the real number comes out people will be disappointed and think it was a failure.
Better to start small and let the number build than the other way around.
From the rally: “We’re turning up the volume . . . President Obama, can you hear us now?!”
