We recently spent a month touring round Mauritius. Early on we took a wrong turn and found ourselves driving past a prison. It had large gates and a high wall with razor wire on top, which was understandable. Then we started noticing a lot of private properties had equally large gates, and quite a few had walls at least as high as the prison, often with similar razor wire on top. The larger the property, the more impressive the fortifications seemed to be, though even the more modest ones had seriously strong looking gates, which were invariably closed. Finally I started noticing a third tier of security on some houses, over and above the walls and razor wire and realised it was electric fencing. This seemed to me extraordinary. Even the prison didn't have that! We spent our last week in and around Blue Bay. This seemed a very tranquil area, but again I noticed several properties with high walls, razor wire and multiple strands of electric fencing. Generally, I felt very safe while in Mauritius but I was aware that all four small self catering places we stayed at shared a common factor of keeping their heavy duty gates shut at all times and expecting their clients to do the same. One place required us to not only lock our room door and the main entrance door every time we went out but also to secure a sort of portcullis affair with spikes on top just inside the entrance with a chain and padlock.
I was left wondering just how accurately these security provisions reflect the likelihood or otherwise of intruders or break ins?
