Uh, that turned out to be 800,000 people, according to analysis of satellite photos by Prof. Stephen Doig, didn't it? The "estimated 1.8 million" was one of those beforehand-estimates-that-turned-out-to-be-an-overestimate-but-let's-keep-it-cuz-that-helps-the-Left. Only off by a million?
Heck there are far more than that every year on New Years Eve in NYC, and even there, it isn’t that bad!!
I heard one fawning newscaster claim there were almost FOUR MILLION people there!
