The failure of their actions (or failure to act) will be on their conscious.
The resources can be people, vehicles, existing roads, boats, helicopters, food, clothing, etc., etc. Considering the circumstances, it would behoove any leader, his followers, and/or others to do the best that they can by using their own talents, energy, resources, etc.,.......that is if the aim is to survive.
You realize that, and you're not even the elected Mayor....for the first line of defense to not use the resources available to him (the Mayor), was just sheer neglect and disregard for the saftey of others.
