Mob Rule: Only 500K demonstrators against Morsi

According to open source calculations at most 500K people can fit into Tahir and adjoining areas. The billionaire coptic christian funding tamarod tweeted 33 million (100x the number) and the anti Morsy media took off and claimed it as truth. The solution would be elections but neither the egyptian military nor the opposition is willing to test their claims in another election.

How Many People Are in Tahrir Square? Here’s How to Tell [Updated]

Tens of thousands of people gathered today in Cairo’s Tahrir Square. Or maybe it was a hundred thousand. Or could’ve been up to two million. Except, by some counts, the Square can’t hold more than225,000.

Every time a ton of people gather in one place, there are all sorts of pronouncements made about how many folks really showed. The figures rarely agree; Glenn Beck’s rally on the National Mall this summer attracted a million people, according to Beck cohort Rep. Michelle Bachman. CBS News pegged it at more like 87,000.

There is something of a science, however, to sorting out crowd sizes. Here’s how it works.

Step one: Get an eye in the sky. High-quality overhead imagery can give a pretty accurate sense of how many people are in a given spot below. For the 2009 inauguration, dueling estimators used everything from aerostats to satellites to snap shots of the masses.

Step two: Take a sample. Focus in on one small part of the crowd, and get a sense of its density. University of Illinois crowd-guru Clark McPhail figures a person can comfortably stand in five square feet. In tightly-packed situations, each person can squeeze into two-and-a-half square feet. Much more than that, and it’s The Who at Cincinnati, 1979.

Step three: Measure the space. Get a sense of the square footage where the gathering is taking place. Tahrir Square is about 490,000 square feet, according to the private intelligence firm STRATFOR. At two-and-a-half-square feet per person — “comparable to the crowd density of a packed subway car” — even 200,000 activists would be pushing it. That figure sounds about right. Maybe there’s a million people protesting in Cairo. But no way could they fit into that single spot.

This three-part method was first employed by a University of California at Berkeley journalism professorin the 1960s, who wanted to know how many anti-war protesters were outside his office. But despite advances in overhead imagery and statistical modeling, the seemingly-straightforward analytic exercise gets constantly mired in controversy.

The National Park Service, for example, used to be the go-to agency for official crowd estimates. Then it pronounced that only 400,000 people showed up to Louis Farrakhan’s “Million Man March.” Farrakhan threatened to sue. And the park service got out of the crowd-guessing game.

For President Obama’s 2009 inaugural, the service relied on the Washington Post’s figure of 1.8 million people. Competing estimates ranged from 800,000 to 1.271 million to “as many as two million.”

Al Jazeera, the most influential news outlet covering the uprising, has revised its original protester count, from two million protesters in the protest epicenter to two million protesters in all of Cairo. But a strict count at a demonstration can be less influential than what networks broadcast. And with Al Jazeera keeping a densely packed Tahrir Square on people’s TV screens, it gives the impression that all of Egypt is calling for Hosni Mubarak’s head.

Update 5:10 pm: Dr. Clark McPhail, one of the godfathers of crowd-sizing science, e-mails in with his estimate:

I used Google Earth to access Tahrir Square in Cairo and the Google Earth Ruler to take some dimensions of the carrying capacity of the “square” as well as what appear to be accesible spaces surrounding it on three sides.

It is actually not square but a greenspace within a traffic circle. Assuming no traffic and that all lanes of the roadway that encompass Tahrir Square are included in the carrying capacity of that part of the venue, my calculations rounded off yield 84,000 square feet. At 5 sq. ft. per person this space could carry 16,876 people. When one looks at the photo, one could conceivable say the density is closer to 2.5 sq. ft. per person. The overhead vantage point of the photo is a useful one. That would yield 33,752 people.

My suspicion is that the gathering spreads out into the surrounding spaces that appear on the Google Earth map. There is a triangular space at the top of the Google Earth image of Tahrir Square as well as into the two polygons below the “square.” The latter are not perfect rectangles but multisided polygons. I did not take precise measures but used to ruler to produce dimensions of the triangle above the “square” and of crude rectangles approximating those polygons below the “square.” If anything this omits some accessible space. The “triangle” would accomodate 14,000 people at 5.0 sq ft, 28,000 at 2.5 sq. ft. The two “rectangles” would accomodate 21,000 at 5.0sq ft (42,000 at 2.5 sq. ft.) and 24,000 at 5.0 sq, ft, (48,000 at 2.5 sq. ft).

Combined the carrying capacity of those four spaces is roughly 380,457 sq. ft. This could accomodate 76,091 people at 5.0 sq ft per persons or 150,183 people at 2.5 sq. ft.

These are crude numbers but I would venture an estimate of 200,000 max for those four contiguous spaces. There are of course several streets that feed into the “square” and the possiblility of another 50,000 or so in those feeder spaces abutting the “square.” I can’t see how 1,000,000 people could fit into this venue.

____________________________________________

The size of Tahrir and adjoining areas can only accomodate 386,000 people at one point in time.

The area of the portion leading from Tahrir to Qasr-El-Nil Bridge to the west of Tahrir square plus the area of the bridge itself and the roundabout near the Opera House according to coverage by Google Earth of protesters presence there would amount to 29,791 SQM.
The area of Talaat Harb Street (East) amounts to 9,919 SQM.
The area of Qasr El-Nil Street (East) amounts to 5,237 SQM.
The area of Champleon Street (East) amounts to 2,212 SQM.
The area of Mahmoud Basiouny Street (East) is 2,840 SQM.
The area of Mohammad Mahmoud Street (East) is 3,196 SQM.
The area of Sheikh Rehan Street (East) is 3,776 SQM.
These areas of Tahrir and the surrounding areas amount to: (72,000 + 29,791 + 9,919 +
5,237 + 2,212 + 2,840 + 3,196 + 3,776 = 128,791 SQM) generally 1.7 person is ideal for PSM but i am rounding off it 3(Maximum) person PSM so total people in tehrir square were on 30 june 386373. this is the first lie told by you and your army ” there are more than million peoples”,this the million………???

Where did this millions of people come from? I request all hypocrites to use their Mathematical brains to take the Google Map and calculate the total area in and around Tahrir Square and ask their consciences as how many people can be accommodated in Tahrir. They are all partners in crime either directly or indirectly.

– Keeping the President captive
– Organizing a mass demonstration, manipulating the numbers(remember Tahrir and adjacent area can not accommodate more than max 500,000 people) and getting help from army to oust the Govt.
– Reluctance to participate in elections for fear of losing and becoming PM, VP etc under an unelected Govt
– Accepting all power in the hands of unelected President but not in the hands of the elected President
– Losing election 5 times and then forcing the President out of power by force.
