there are always crazies.
but you know what? - they will be held accountable.
I'm not sure why people figure that if "zombie days" suddenly arrive, then they can get away with anything. Truth is ... armed robbery is still armed robbery, murder is still murder. If you take a look at the bad stuff that happened in New Orleans (during the Katrina emergency), after the disaster - people were prosecuted. Victims remember, police make arrests.

There will always be a return of 'law and order'. That's what the crazies seem to forget.

In the unlikely event that Hawaii was really hit by a nuke, the US assistance response would be massive. There would be a lot of National Guard there - to deliver supplies, do evacuations, and enforce the law. There is no possibility that people will be forgotten ... it would be the other way around, IMO.
