     I actually believe in some respects we may be in danger of working too quickly, simply to address that perception. As the ridiculously over-used cliché notes, Rome was not built in a day.

For a community still suffering, still shocked, and literally still shaking, there clearly needed to be a plan put in place as quickly as possible.

Earlier uses of the proverb tend to be in the form Rome was not built in a day.
