I and my family have been regularly using this alleyway for over thirty years, at all times of day and evening, and we have never encountered anything untoward. Lighting is however a problem - or has been. The last time I walked along it in the dark, I think that two of the street lamps towards the top end weren't working, leaving a long dark stretch, bordered on one side by shrubs and trees where miscreants could, in theory, easily be hiding. I know I should have reported this to the borough, but when on a previous occasion I tried to do this they wanted the code numbers of the defective lamps, which I didn't know and couldn't have seen in the dark anyway. (OK, I could have gone back in daylight to check ...)
