So 2 more this afternoon.
Bloke on 5 Live this morning, ex black gang member, now a social worker, nailed it. Even though it was an uncomfortable listen.
He explained there is currently a "war" (his words) between black East London and black North London gangs. Mainly drug related, but also fed by social media spats. (Dont disrespect me sort of stuff).
He said that every time there is a stabbing/killing in one part of the city, there will be one in the other part. Asked if the Met knew, he said, to paraphrase, "If not, then why not, cos everyone else remotely connected knows".
Like I said, uncomfortable.
