Pre-planning is excellent, but I'd be willing to bet that no matter what is mandated, the severity (or perceived severity) of a crisis will be inversely proportional to ones rights. If power and authority is there, it is likely to be used. Its not like you can really do anything about it, but awareness always helps. I mean, the last thing you want during a crisis is to be tossed into the can for complaining the authorities violated your rights under such and such clause.
