A set of terrorist bombings on public transport in London is a nasty reminder of the risks of holding international events on home soil, and is particularly poignant the day after city was awarded the right to stage the 2012 Olympics.
It's likely the outrage was aimed at the G8 meeting in Scotland and the UK's continued involvement in Iraq.
We at the Pigs are shocked by this event, are thinking of the victims and sincerely hope the casualty numbers are small.
I was in London when the IRA were bombing but there wasn't much as bad as this in London - except perhaps for the attack on the Life Guards which had maximum impact with maimed horses too. And at least the IRA usually gave warnings. To me the most shocking thing then was seeing 2 policemen closely examining a discarded cigarette pack in an underground corridor. I also recall getting to my parked car as 2 others reached theirs in the same street. We all ducked down and looked underneath, looked sheepish and got in and drove away. It became a normal part of life for a while. A friend of mine from Belfast said the hardest adjustment when returning from a family visit was being able to walk past a parked car without fear.
But together with the bombing in WW2 it's given people a stoicism which is remarkable. And I am so impressed with the response of the emergency teams - the calmness, the well rehearsed planning. So many lives must have been saved due to that - and being in an area stuffed with hospitals helped too. There are times when I'm proud to be a British citizen.
