Do you have any idea how much sheer panic an attack like this would have in the US? Did you know that New York considered shutting down it's subway system the day of the first attack in London? Police were put on busses in Denver, Dallas, Kansas City, and several other major US cities that day. Do people in Kansas City actually believe there will be a coordinated terrorist attack against them because a few bombs blew up half a world away? Sadly, yes.
In London, it's a shock to people, no doubt, but you do not get the incessant, unreasonable level of public panic that other major cities do.[/
