Bags there are many caring workers representing charities and public sector organisations working at night to help the homeless, and London has the highest representation. I've worked on a rota myself when I was a probation homelessness volunteer, homeless centre worker, and then a probation officer, along with Lifeshare, Salvation Army, CentrePoint, Buddhist groups, council staff and lots of other people who were willng to go out at night to offer support and practical help. Councils have routinely changed ther homelessness policies, but there have always been people on hand at the frontline to assist, so the police have no excuse for going in there the way they did.
