According to the BBC news, nearly 30 people have died in a series of terrorist bombing of London's transportation system. This is a horrible tragedy, but I'm glad to know that Mark is ok. You should read his post on his reaction to the bombings. Mark provides excellent perspective on this terrible day for London.
"Yes, every single bomb went off somewhere where I would regularly be. Yes, I am angry. Yes, it is cowardice. Yes, it is sick. Yes, I am worried about a lot of people. Yes, it is a waste of life.
Will it change my mind about Bush and Blair? No.
Has it changed my mind about war? No
Will I ever blame all Muslims? No." - Mark the Recidivist
