We should form public policy on the basis of evidence – that is to say, models that have high explanatory power and confidently predict reality correctly.

We have policy around nuclear attacks that aren't based on actual nuclear attacks. There are policies around preventing certain people from being assassinated even if nobody's assassinated them yet. If “swatting” is something that we know happens in this sort of case, we should review our procedures around preventing it if circumstances change in a way that we could reasonably expect would increase swatting.
