Logically, adding in the frequency works - I totally agree. In reality, though, people don't understand frequency and how it applies to them which is why we get into these security theater situations in the first place.

Or perhaps they do. Frequency works when assessing statistical risk for a population. Statistics work for populations not for individual instances. The fact that my chances of being attacked by a dog are statistically low are little solace when faced with a frothing mad pitbull.
Ultimately individuals want to preserve themselves (and family/friends) not simply preserve a high proportion of the population.
