And the notion that “officials” wouldn’t have thought of things like that (families) in their selection and enlistment of guards is questionable.
You first have to believe that those in power don’t give a crap about the masses, that they will keep very needed information from them to the very last second, and that they have already thought of all the “I’m out for number one (wrt guards)” scenarios. I believe that’s what they will do. They have plans for it..... continuity of government and all that.
The Russians take a different approach. They have shelter space in Moscow and St. Petersburg for every citizen of those cities in deep subway tunnels with blast doors and propositioned supplies. This says something about which country values it’s citizens now doesn’t it.
Check out the size of this door that’s at least a 500psi door which means effectively a direct hit wouldn’t bust it open .

“They have plans for it.”
Yup. They have plans.
The problem is that no plan survives contact with the truly crazy and weird—and a nuclear attack will confound even the best plans.
Example—There are plans to get Congress out of harms way by getting them to underground shelters.
Problem—That assumes that there is time to contact them and time for them to get to those places. With disrupted communications and panicky individuals in the chain of command Murphy’s Law starts to kick in... (anything that can go wrong will go wrong).
