A terrorist attack is basically impossible to predict, says the Risk Management Monitor, but, even so, the risk of loss from attacks at sensitive installations can’t be dismissed. A specific property’s risks can be assessed, and should be, even though an attack can’t be predicted.
This is an extension to a baleful extreme of the basic principle behind insurance in general. Risk vulnerability is harder to apply to terrorism than, say, the possibility of a hurricane striking a given locale. But, insurable or not, when terrorism is coupled with other types of unwanted intrusions, the risks of hostile invasion of sensitive property are real enough. Sufficiently real to justify protection, if not from insurance, then fencing, guard stations and reliable vehicle barriers.
