Dom, you obviously don't live where we live, the only thing to frighten us would be the owls, bats and things that go bump in the night, not a shop in sight, so unfair comparison to London, Calis/Fethiye is bigger than our village or town! also we have not had the break-ins or assaults around here, our village, to those reported in the last 12months compared to that of Fethiye.
When we lived in Akarca I used to say that I did not mind walking around late at night or Fethiye and Calis, would I feel that way again, no, I would be more wary of my surroundings.
Any form of public "Mob" gathering is frightening, and invariably someone will get hurt. albeit UK, Turkey or any other country, when a native tells you, as a foreigner to stay in, that tells you something.
You don't hear much of serious assault against the ex-pats, yes they do happen yet are rarely reported to police or reported in then press, for reasons best known to the authorities. Yes I feel safe in the UK.
