Yeah. Seems I recall reading about London having “No Go Zones” because of crazy Muzzies.
Overhyped semi-myth. There ARE areas where extreme Muslims have tried to take street control and are a problem, but most have been dealt with and jailed. They remain a problem, but no quite on the level Trump would have you think. UK police do NOT ignore areas (esp Muslim), but there are areas where police have to be more wary. Just like the US or any country.
Also there are no-go/dangerous areas where the no-go is caused by white and black youth, and they have always existed in the tougher UK cities like Glasgow, Liverpool, Manchester and of course London. ‘Dodgy’ as we would say. Where the police are hated.
