@Baldimo,
Really? National Monuments, of which the WW2 memorial is one, are run by park rangers. The National Mall is run by the Park Police and has no rangers. National Monuments typically have rangers on site to watch, answer questions, and assist visitors. The National Mall has no reason to have rangers. When the park rangers were furloughed the national monuments were closed. The National Mall was not closed. The Park Police still were on duty because they are considered essential under the law. The Park police are the ones that approve and police activities on the Mall. WW2 veterans could be on the Mall all they wanted. They were refused entry to the areas that are under the control of Park Rangers who were no longer on duty because of the shut down.
You are re-writing history. You are confusing the National Mall with National Monuments. They are not the same thing. None of the illegal immigrants entered the WW2 memorial. They were restricted to the Mall outside the Monuments. None of the veterans entered the WW2 memorial. They were restricted to the Mall outside the Monuments.
The 2 groups were treated exactly the same in the areas they were restricted from entering.
