Thanks for the reminder Izzy, I read your post just in time. Actually it will be at the midday here though.
It gave me a chilling feeling as I have been to all those tube stations, especially I always stayed at a B&B very near Edgware Rd., so I was there like a daily basis. That particular stop is rather small, I suspect that probably the culprit planned on planting the bomb at Paddington but something didn't work out so moved one station down. I am sure the things could have been much worse if it went off at Paddington, another major hub like Kings Cross.
It is so sad that violence never seems to cease in this world. Do they ever stop and reflect just what they are trying to achieve by commiting such horrible things?
