If your constitution proves to be ill-designed to the point of not allowing citizens to keep their homes during a crisis, or, as the case may soon be, not allowing actions from the government that will save tens of thousands of lives...isn't it time to give the whole thing a once over, see what assumptions from 200+ years ago don't hold much water today, and give the whole thing a rewrite?
Amazingly, you wouldn't even need a coup to do this, which is a testament to the framers sense.
But they seem to have left behind a bunch of people who'd rather use the Constitution as some sort of untouchable religious book you claim adherence to to score political points.
Can't imagine why you're suddenly shocked at insane tricks administrations have to pull to get things done. This isn't new, is it? Sclerosis has been building and building. And it'll continue to build, unless you change some things as a nation.
