Technically speaking, they could probably make a case (keep in mind, this is personal analysis, not something put out by TSA or DHS) for the area around any of the stops for that bus - especially if they have intel indicating that a credible threat to that type of location exists. Realistically, I do not see them doing VIPR stuff for much past mass transit lanes (such as a subway hub, bus hub, etc). I am almost certain there is a mass transit station on Vikings plaza, and that the VIPR was most likely there, but again, that is simply what I think, as I have no specifics to back that up. Again, I do not see the situation you describe as something that is on the way primarily because it is a wrong thought process, secondarily because it would crush the economy, thirdly because there are not enough people to do what you describe, fourthly because the government does not have the money. This is just not a feasible thought process for the next 20 years at least, because there has not been the type of entrenched dogma and programming of the public that would be required (there would be way fewer dissenting sources out there if this were the case). We Americans have a stubborn streak that is famous, we are (in generalized terms) polite, helpful and good natured... right up until you start telling us what to do en masse (or threaten us as a whole). Look how quickly the differing sides came together after 9/11, everyone was helping little old ladies across the street again, democrats and republicans were drinking in the same establishments, congress worked together for what they thought was the best direction at the time, people went out of their way to do decent things. Fast forward to now, there is a huge divide in this country because there are more and more situations of the recognized governmental structures "telling" people what they can and can not do. Our history is rife with things like this, where the government overreaches the needs/desires of the nation, and the nation begins to show fractures along the edge, and begins to force societal corrections on the recognized governmental structure. I believe we are reaching a point where the self correction will begin to come into play - how that comes about, I am not certain. I am pretty certain that armed "revolution" is pretty much off the table for the foreseeable future (unless they really force the guns issue and start storming Johnny citizens place and collecting them from law abiding citizens under force, then you may see one), and there does not seem to be a seismic shift in political attitude, so we may not have reached critical mass for the correction yet.
