It isn't everywhere though is it? Newcastle is like a breath of fresh air to walk around, Manchester is filthy and dangerous.
Newcastle is a fantastic city, and the people are some of the best, my Mrs is a Geordie and we go visit her folks regularly, great city and great people.
But i've never felt afraid in Manchester. I'm originally from Nottingham, the town i used to live in has gone to the dogs, knife crime in Nottingham city center was always a worry. I was one time jumped by about seven or eight kids... and they were kids, one black lad and a bunch of whites, with hoodies, all playing the gangsta. They were going to 'cut me up' and 'f*** me up' - i just laughed at them, it was quite a ridiculous site, tbf.... i have good friends in the Meadows area of Notts, they've all seen knife crime at first hand, all know someone who has been badly effected by it.
I've never once felt Manchester was a dangerous place - and certainly no more dangerous than a lot of other places.
