> Firstly I would not go back to London unless I had the protection level of a government Minister. My life is not worth any amount of money and violence is out of control.

I feel like there's heavy observation bias here. Maybe you had a bad experience or two, but I've been living in London for the past 4 years and haven't had any such encounter(s) so far. You make it sound like London's some third world warzone; I personally felt that New York, SF, and LA were far more unsafe when I was living there with the amount of homeless people and fentanyl addicts walking around.
