So church friends' relations were in a cab in Russell Square when the murderous knifeman ran towards it. The cabbie locked the doors.
Every time there is sudden violent stranger attack like this, I do a quick mental assessment of who is where. The Bataclan massacre was the really frightening one, and I was so relieved when the "So and so is safe" feature appeared on Facebook.
I feel really awful for the relatives of the poor American woman who was murdered, and the others who were stabbed. Nobody expects this to happen to them on holiday in London.
