None of the homeless people in my town seem to be from here. They don't speak with the local accent; they speak with the generic London "druggie" accent. (The local accent is quite easy to recognize)

This is a nicer town than London, generally; at least, it is in the centre, where the homeless people concentrate. The police seem very tolerant of homeless tent-dwellers. There was a small encampment around the corner from where I live, camped directly outside the courthouse and opposite the police station (!), for about two months. I found them rather intimidating - they were very shouty.
