We were just @ that stop yesterday. Got off and walked east to ice skate at Bryant Park. The station itself during rush hour is a mass of people. Yesterday, with Christmas tourists, I kept having the thought of how some maniac could do all kinds of damage if they are committed. On Saturday night, we actually were at that stop too, and walked all the way to Rockefeller Center to see the tree and the Saks building show. Same deal. The police have everything barricaded, but with the mass of people (you can barely walk), I kept thinking about how it is a massive "target." I know this is different, but I have long wondered when idiots would start targeting subway stops.
EDIT: I hadn't read enough before posting. Looks like it was at the Port Authority or near the Port Authority. If it was in the Pot Authority, same deal. So many people are hustling through there in the morning.
