Gang on gang violence in London among the black youth is a thing. It are usually stabbings and a mate of mine who works for a hospital in London always comes with the craziest stories how and where someone gets stabbed in creative places. And this happens every other day, it doesn't faze him.
As for this Sasha character, she is in a risk group and she has some weird ideas about the roles people should play in society. I do not condone violence and I didn't want her to get shot. This said, the incendiary things she does say is a health hazard.
