BaC - I am not even going to go into your tree size estimations
Why not? You raised the issue of trees and I tried to give your concern the benefit of the doubt. Now all of a sudden you want to drop it?
and belief that 87K people would be gathered at the mall and not a single toilet would be available
Which of course I never suggested. I just noted there are no toilets visible in the open areas. I'm sure there are toilets in the area. But even if there are toilets, do you honestly think the amount of area they cover is any sizeable fraction of the total area?
I will show you what appears to be nearly the entire crowd seated in lawn chairs like a day at the beach!
Ok, I will admit those folks in that photo are sitting and occupying more than 2.5 sf per person. And looking back over the various images I've seen, I'll admit that other photos (such as image 3 from
http://www.glennbeck.com/content/articles/article/198/44954/ ) show people sitting (either in chairs or on the grass). But that doesn't represent the "entire crowd"?
Look at the 5th through 8th photos here:
http://www.glennbeck.com/content/articles/article/198/44950/ . Images 5 and 6 show people near and under the trees on both sides of the pond. These people are standing close to one another … closer than they would not be able to do were there chairs in these areas. Image 8 is another view of people on the right side under the trees, from a location quite close to the Lincoln Memorial. And again, these are people standing very close to one another. I see a wheel chair bound person but I do not see any chairs. Image 7 from
http://www.glennbeck.com/content/articles/article/198/44952/ shows people under the trees standing shoulder to shoulder. Image 9 from
http://www.glennbeck.com/content/articles/article/198/44956/ also shows people in the trees on the right side of the pond. Well back into the trees. And these people are clearly standing in close proximity to one another. Photo 10, below that, shows the same thing. People standing shoulder to shoulder, something they could not do if the "entire crowd" was sitting on chairs. And as far as the folks next to the pool is concerned, Image 7 of
http://www.glennbeck.com/content/articles/article/198/44950/ is near the pond on the right side, but back where the second of the TV screens on the right side is located. These people are clearly standing in cross proximity to one another, something they could not do were there chairs. So at some point down the length of the pond, people may be standing, not sitting.
But I will agree that my calculations need modifying.
I'll start with the crowd that is next to the pond. I'll assume it consists solely of people sitting in chairs. How much space does such a person occupy? 15 sq feet per person seems more than generous for the chair and space between chairs. Agreed? At that density ( I'm ignoring the possibility that at some point, the crowd along the pool transitions from sitting to standing), the area that is visible on each side of the reflecting pool before reaching the nearest trees … which my eyeballs still say is about 6/10ths of the reflecting pool in total width … would comprise a crowd of about 2029 * 167 * 0.6 / 15 ~ 14,000.
Next, I count the people that are in the trees on both sides. The photos seem to suggest that most of these people are not sitting but standing. Based on the photos, I suggest those people are standing in a crowd of "average" density according to the Park Police methodology … i.e., occupying 5 sf on average per person. Clearly there are many people standing much more densely than that but there also are people standing less densely. And just to be conservative (from CBS' perspective) , I'm going to assume a figure of 7.5 sf per person in this portion of the calculation. Sound fair? Now I pointed out previously the regions with people under the trees on both sides of the pond is more than equal in width to the reflecting pool itself. The photos all seem to suggest that is true. But I'll be a little more precise this time. Looking at image 1 in
http://www.glennbeck.com/content/articles/article/198/44950/ , my eyeballs say that combining the width of the band of trees on the left with the width of trees on the right out to where gaps in the trees still show dense crowds is at least 25% greater than the width of the reflecting pool. Using all of that data gives a crowd of about 2029 * 167 *1.25 / 7.5 = 56,000.
Next, one of the photos that I previously linked (a link that is unfortunately no longer working) showed there were crowds gathered on the right side of the pool near the Lincoln Memorial that were almost twice the width of the reflecting pool from the reflecting pool itself. This was probably because people viewed that area as a good place to see the podium which is nearby. Image
http://i.dailymail.co.uk/i/pix/2010/08/28/article-1306961-0AF38360000005DC-7_634x420.jpg certainly suggest that the crowd viewed that side of the Lincoln Memorial as a good place to view the activities. Now the above places a crowd about 75% of the reflecting pool width further out from the area that has already been counted on that side of the pool. But I'm only going to assume it's another 50% of a pool width out. And the previous image that I'd linked suggested that portion of the image with people extended down about 1/3rd the length of the pool from the Lincoln Memorial, but let's assume it only extends down a 1/6th of the way. Then, assuming that the density of the crowd is the same as just used above … 7.5 sf per person, that region would add another 2029 * 0.16 * 167 * 0.5 / 7.5 = 3,600.
Next, on the left side of the image, I see a crowd in the large open area on the other side of the trees that are nearest the reflecting pool. That area is about 20-25% wider than the reflecting pool. The density of people in this region looks to be about the same over about 2/3rds to 3/4ths the length of the area. Let's just use 2/3rds of the pool length. And in those areas, the density appears to be close to that next to the pond. In other words, I'll assume people are sitting down on the grass on something. I'll even conservatively (from CBS' perspective) assume the density of people is only 1 person per 20 sf. With that assumption, the crowd in this region is at least 2029 * 0.67 * 167 * 1.2 / 20 = 14,000.
Now the number of people in the other 1/3rd of that area is admittedly much less. My eyeballs suggest a about 2000. Fair enough?
But now we have some areas that haven't been counted before. There are a large number of people at both ends of the pool and off to the left and particularly right (looking towards the Lincoln Memorial) side of the Lincoln Memorial.
The crowd between the pool and the Vietnam Memorial (and extending to the trees beyond) appears to be standing shoulder to shoulder and about 5 to 10 people deep. That would produce a total of about 1.6 * 267 / 3 * 7.5 people = 600 people.
The crowd behind the Vietnam Memorial, by visual inspection, numbers in a few thousand. Assume 2000 in total.
The crowd on and around the Lincoln Memorial also, by visual inspection, also numbers in the thousands. For example look at
http://i.dailymail.co.uk/i/pix/2010/08/28/article-1306961-0AF38360000005DC-7_634x420.jpg
So let's see where I stand now.
14,000 + 56,000 + 3,600 + 14,000 + + 2000 + 600 + 2000 + 2000 = 94,000.
Given that is within CBS' error bounds, I'll now accept the CBS estimate as legitimate (sorry CBS for doubting you). Just for confirmation, I'd still like to see the high res photos they used. To see if their resolution is adequate to do the above, or whether they just got lucky. Because frankly, I have no more trust in CBS than you do in FOX News.
