I was reading a post by Ross Anderson on his dismal experiences at John Lewis, and ran across the term security theatre, I’ve actually heard the term, before, it was orignally coined by Bruce Schneier, but this time it got me thinking about how much activity in the safety field is really nothing more than theatrical devices that give the appearance of achieving safety, but not the reality. From zero harm initiatives to hi-vis vests, from the stylised playbook of public consultation to the use of safety integrity levels that purport to show a system is safe. How much of this adds any real value. Worse yet, and as with security theatre, an entire industry has grown up around this culture of risk, which in reality amounts to a culture of risk aversion in western society. As I see it risk as a cultural concept is like fire, a dangerous tool and an even more terrible master.
