Right, so we would expect the magnitude of the changes from 9/11 to be about 1/14th the magnitude of the changes we do to prevent car deaths.
We have a whole licensing apparatus and traffic policing as well as safety regulations for vehicles driven on public roads. It's not cheap.
Maybe if you have zero understanding of things like emotion and humanity, and also cannot tell the difference between an accident and a mass murder.
Otherwise, this is surface-level insanity.
