I wasn’t referencing any posts in particular, certainly not yours.
What I would say is that crime rate is not always an accurate indicator of criminal activity. Particularly in small communities like this, I think you’d see a lot of crimes going unreported because they’re either seemed too small to cause trouble over in a small place, or they’re ‘sorted out’ without police involvement because everyone knows who’s responsible.
So there could have been a lot more going on that would justify the need for CCTV (if you can afford it of course. Shoreline properties are generally the most expensive) despite the actual crime rate being statistically low
