One of the first things that I noticed when I visited Rio de Janeiro a few years ago was the clear fixation on safety and security. There are gates and cameras everywhere. And the guidance you tend to receive from the locals usually resolves around how to stay safe. Don't wander around at night. Be careful when you take out your phone. Be mindful of certain areas. You know, those sorts of things.
Of course, you never really know how dangerous a city is because it's one of those things that's impractical to test. You're not going to wander around dark places just to see what the probability of being robbed is. The more sensible thing to do is simply believe what people are telling you and you observe the cues scattered around the built environment.
The result is a general sense of anxiety. You're not quite sure if all the gates and cameras are truly necessary, but their mere presence makes you believe that they might be. I mean, why else would they be so pervasive? Or, could it be that people are overshooting with their investments in safety and security because, well, fear and paranoia are strong motivators?
I was reminded of all of this as I read through Ed Chartlon's recent book review
