Boston Police Inspect Commuters

pacalis writes: The New York Times reports that "in Boston, police will begin inspecting passengers' bags on the subway system... not in response to a specific threat against the transit system here, but to the general threat of terrorism." Today, are people more affected by the threat of terrorism, or the day to day interaction with police hunting through their bags? http://www.nytimes.com/2006/10/05/us/05boston.html
