This is code training for 1 thing and 1 thing only.
Civil Unrest.
Government Officials/Law Enforcement/Military use the zombie apocalypse as a quasi-humorous way of openly training their personell for an economic break down.
We the people see this and roll our eyes or chuckle or even say, hey cool! Where do I sighn up!?
But think about it.
One day you wake up and everything that was good and orderly is no more. Those people who were not prepared are now running wild through the streets killing and looting. Gangs form and attack smaller groups or families that are perceived to have food/weapons/ammunition cached.
The first things to go are banks then stores then perhaps hospitals after that they will move against government targets.
Are the Government workers immediate families caught up in this? No, because the government is very proactive in making sure that Police and Soldiers take care of their families. Family Care Plans are required within the Army. You need to show that your children are taken care of incase you are called to duty. Classes are given on prepping for disasters and so on. Nearly every reserve/national guard drill will cover Family preparedness each drill.
Government officials once they reach a certain level have escape routes or resources to hold "Zombies" at bay.
Then their's reacting to "Zombie Bite Infection". This is code for Sympathizing with the plight of the citizen. In real life it is litteraly the expression of such symnpathies and requires the immediate separation of this individual from his cohots so that he doesn't infect them with his doubts.
There are Field Manuals that cover these things. I'm not sure what their numbers are. Very good reading.
"Laws that forbid the carrying of arms . . . disarm only those who are neither inclined nor determined to commit crimes . . . Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man."
--Thomas Jefferson, quoting Cesare Beccaria in On Crimes and Punishment (1764).
