Socknickingpixie I am so sorry to hear about your horrific experience. Thank you and everyone else for sharing their experiences on this thread too.
That link has a fairly odd view of risk management. If I were given something like that by a student I'd send it back with lots of red ink and be worried that they really hadn't understood the discipline at all. Risk management is not about minimizing or even primarily about reducing risk. Life is all about taking risk, we do it all the time, frequently because we anticipate that we will be rewarded by achieving our objectives (in this context finding a partner, having an enjoyable evening out or simply going about our daily lives). Risk management is about being aware of risk, analysing it for a better understanding, evaluating the likelihood and consequence and then taking reasonable action in order to achieve our objectives in the light of the uncertainty/risk.
Most risks have multiple causes, for rape there are in general fundamentally two. One someone: who wants to rape. Two: someone who can be raped by that person. You need both for a rape to occur (in the same way that for fire you need a heat+oxygen+fuel). All the rest is really essentially noise.
For whatever reason all the focus is on the latter, as if if only there weren't people to rape it would all be just fine. Which is frankly rather bizarre. If in my professional capacity someone presented such a lopsided analysis to me I'd tell them they needed to do some more work. For example when there are known rapists on the loose why is it never suggested that all men are under curfew while they look for the rapist? No men about = no rapist (assuming that they have enough victim reports to know that the rapist is a man). It's always women that are told to moderate their behaviour, taking on the frankly more likely risk of excessive fear, curtailment of activities, and somehow the blame for the rapist because if only there weren't any women the crime could not occur.
The risk of being raped is a high lifetime risk, but the risk of being raped by a stranger on any one trip away from home is very very low. Knowing the risk and accepting that there is little you can do but choosing to live your life the way you wish to anyway is as much a way to manage the risk of being raped as wearing a burka and never being alone. The effect on the likelihood or the consequence of being raped is almost certainly marginal. The suggestion that changing your behaviour in this sort of manner is 'excellent risk management' and not doing so is 'poor risk management' is factually incorrect and absolutely victim blaming. There simply are some risks that we as individuals can do very little about. It's a bit scary, but we have to live with it.
Oh and bumbley I won't be telling either of my children not to walk home alone, as I walk by myself on a regular basis. I am not 'putting myself at risk' my body is not some sort of lure that needs to be removed from public.
