I visited London several years ago. It is a magnificent city. Part of it's magnificence is that you can stand on a corner and watch half the world pass.
What AlQaeda did was several different kinds of stupid. To kill civilians of all races and nationalities. To turn the attention of world leaders from global warming and the poor of Africa to terrorism. To create martyrs and make themselves villains to much of London was stupid stupid stupid!
My sympaties to the people of that great and gallant city.


Incidentally, if you can find a copy of Julie Andrews, "The Lass With the Delicate Air", you'll hear a wonderful rendition of "London Pride". Ms Andrews was a fine singer.
