in this sense of London, having lived there myself, and in fact transitioned there. It felt safe to do so because, basically, in London, everyone's already seen it.

(Of course, Bristol's even better in that regard. I would say that because I live here, but a friend who moved from here to San Francisco reported back that it "felt" like Bristol, specifically in the easy way it has with people who are different. (Also the hills, the harbour, and the suspension bridge, though ours is the first, of course...))

I expect this case is going to turn out to be some personal dispute that came to a head between two people who knew each other, rather than a general or randomised hate crime.

Although one should always leaven that with caution. Just google "london nail bombing". :-}
