> Denial of this service to people who would not submit to a search, IMO, makes this highly coercive and the search can no longer be considered strictly voluntary I agree with you, which is why in the grandparent post i said "kinda." I think it is a HUGE constitutional stretch to not have freedom of movement on public transportation systems. Roads and sidewalks are public transportation systems, so why shouldn't we have constitutional protections on public subways/buses? The next level of chipping away at this is to have quasi-goverment agencies (government owned corporations, etc) like the one controlling the GW bridge. It pissed me off when the GW bridge used to have signs that said "Photography is prohibited." I really wanted to start a website collecting photographs of the GW bridge, just to show how useless the ban was.
