Well yeah I just read the rest of it by simply following the links at the bottom of the pages you linked and that's what happened. She was legally charged and such, the ACLU got her off by making it a high profile case (rightly so) and quicly pointing out that the defendant had no intention of entering the fed facility but the bus she was on passed through it. If the feds in denver are smart they'll fix that cause its right unfriendly.
The arresting federal officers made a mistake that isn't pointed out. She should have been offered the option of simply walking away (not enter the facility) or taking a bus the other way. That would suck though, maybe all this hubbub will fix the problem they have with their bounds overlapping a public transit system that should be freely traveled.
