that classic proverbial british stiff upper lip. is the tube open? is the subway open? i actually haven t heard that. i was just in a shop and people were talking, the man, his credit card machine wouldn t work and speculated to customers there must be something going on, right across the river and right next to a huge amount of police cars, so clearly the word isn t getting out to everybody. so the tube and bus system have been diverted and probably not going to be driving into the closed roads but as far as i know, most of the stuff is still functioning. most of the commuters, rail and tube system as far as i can tell seem to be working. people seem to be heading home as they normally would. there doesn t seem to be a lot of distraction. nobody s asking around trying to figure out how to get home or rushing for cabs. everybody just seems to be going as normal. matt bradley and westminster, security analyst joins us from
