Gee, gridlock...looks like you "get it" now too... :-)
Question...is it still an "open" facility or "closed" facility? If it's a "closed" facility, then where's the registration of every passenger? If they aren't doing that, shouldn't the "official" be charged with violating the first section?
The protest needs to go to the transit authority now, pressuring the city not to send its buses into a Federal facility. At the very least, they need to put up signs warning passengers, and understanding that by driving on the facility road, they are not serving the needs of those passengers who choose not to provide ID.
Oh, yeah. I'm all for effective security for federal facilities. Running a public bus through there makes effective security a very difficult problem. It is simply not feasible to do a good job screening that many passengers in a timely manner.
Far better to segregate the through passengers from the facility, and only process the ones who are actually entering. And that can be done while the passengers are on foot, so you can fold/spindle/mutilate them and check all their hand carried items as well.
I'm thinking they could build up the guardhouse on Gate #4, and do a walk-through magnetometer and package screen at that point. The could screen all the mail that enters the facility as well. Then the passengers can get on the shuttle bus inside the gate and proceed to their destinations.
Simple, straightforward and effective. Just because the government has the authority to check all the IDs on the bus (and they do) doesn't mean that is an intelligent policy.
