1-She was on Public Transportation, NOT a POV.
True, but irrelevant. I never said she was. I was using the POV example to point out the illogic of saying she was not on government property just because she was on a public bus. The means of conveyance is irrelevant to the question of whether or not she was on a government facility.
2-Public Transportation travels on a fixed route, thus it is not a discresionary route.
True, but irrelevant. She has the discretion to take or not take this bus, if she does not wish to comply with the lawful and reasonable security requirements of the federal facility through which the bus passes.
3-This route traverses a Federal Campus NOT a Facility.
I fail to see the distinction. The campus, facility, whatever, has controlled access with ID required. If the word "campus" is meant to imply that it is open to the general public, that is simply wrong. Access in controlled.
4-Her paid ride goes through the Federal Campus. She never exits the Bus during this portion of her paid ride.
True, but irrelevant. Early on, I was under the impression that the Park & Ride was inside the gate, but it is not. But that doesn't matter anyway. She is on the federal facility while the bus traverses the campus. She could get off the bus in the campus at an uncontrolled bus stop. The government has a legal power and responsibility to control security at the federal facility, and is only requiring compliance with this legal power and responsibility.
5-At no time is she in a Federal Facility, she is in a Bus traversing a Campus.
This is simply not true. The "campus" is the facility. The road on which the bus travels is inside the facility. It is not a public road. The gates through which the bus passes on entering and exiting the facility are owned and controlled by the government. Just because she is on a public bus does not change the fact that she passes through these gates and is inside the facility.
Does the word "Welcome" imply anything? How about when it's "Visitors Welcome"?
