Preventive vs. Reactive Security
This is kind of a rambling essay on the need to spend more on infrastructure, but I was struck by this paragraph:
Here’s a news flash: There are some events that no society can afford to be prepared for to the extent that we have come to expect. Some quite natural events—hurricanes, earthquakes, tsunamis, derechos—have such unimaginable power that the destruction they wreak will always take days, or weeks, or months to fix. No society can afford to harden the infrastructure that supports it to make that infrastructure immune to such destructive forces.
Add terrorism to that list and it sounds like something I would say. Sometimes it makes more sense to spend money on mitigation than it does to spend it on prevention.
