The comment about Londoners is a bit unfair - I lived there for 16 years and of course people felt sorry for those involved in disasters in other partsof the country - Hillsborough shocked a LOT of people, as did the M1 plane crash, the Herald of Free Enterprise sinking, Heysel stadium, Lockerbie... every disaster. If a public mark of respect was organised for another part of the country, I'm sure many Londoners would join in.
However, I am uncomfortable with the way silences are becoming routine for disasters. It was very moving to see people standing out on the street at noon... but the silence was orginally for the end of WW1 and WWII 'lest we forget' ie to remember those who had sacrificed their lives and resolve to prevent anything like that happening again.
We aren't in danger of forgetting the victims on Thursday yet - and we weren't in danger of forgetting the Tsunami victims when we had a silence for them either.
As for sacrifice, the poor people who died and were injured weren't making a sacrifice, they were just trying to get to work. And I wouldn't want to dignify what the bombers did by in any way at all linking it to the idea of sacrifice.
I''m concerned that we are diluting the idea of the traditional silence. Last Thursday was a terrible, terrible day but I'm not sure a 2 minute silence is the correct response.
