Charities? Doubtless in due course there'll be some kind of local collections for the families of those affected, but giving money really isn't the point as far as the London blasts are concerned. If you'd like to feel "useful" - though I'm not sure why you expect that to be possible - why not give to a charity dealing with long term poverty in the developing world, or better still lobby the US government to increase its aid levels and remove trade-distorting subsidies? A rich developed nation like the UK really doesn't need your assistance even in our present emergency, though we do thank you for your prayers. As for the bodies in the BMA building (where I once used to work), Dr Lawrence Buckman had been attending a meeting there and was on the scene ahead of the emergency services. He said on the lunchtime BBC news that 10 people died there, not all of them immediately. Since then this news seems to be being suppressed - haven't seen it officially confirmed at all.
