As you are probably aware, London has had another terrorist event. Car bombs, undetonated - thank goodness!
It set me to thinking about the risks of living in a city that is at the top of the list for these sort of crimes. I love London and I wouldn't want to move just because of a possibility of danger. Anywhere I live will have an element of risk... buses, trains, planes, industrial plant, murderers, branches falling from trees, etc. So why leave the place I love for fear of something that may happen.
I do believe there will be more successful attacks on London. But I figure that if I live as safely as I have control over, and be vigilant, then I whatever will be, will be.
I love London and am willing to take the risk to enjoy the lifestyle that I currently enjoy.
