Thanks for posting that. Have been a few problems recently down here in South London in recent times according to our local newspaper.. There was another trans person killed in Thornton Heath a while ago and a really bad rape in Streatham Hill just down the road from where I live that went to trial about two weeks ago.
This map is interesting, one can search for different types of crime and how close it is to where one lives. Thankfully the high crime area is at least 100 metres from me
