The fault is not that of the Constitution, but of all of us, for the last couple of generations, who weren't vigilant in seeing to it that it was constantly safeguarded.
The Constitution cannot defend itself. When the stewards of this government, from the President down to the rawest military recruit, take their oaths of office or of enlistment, they swear "to protect and defend the Constitution."
That ought to tell us that there are things from which the Constitution must BE defended.
Too many have been asleep at the switch. It is not the fault of the Constitution; that document is sacred and as near perfect as the mind of man (in concert with that of God) can conceive. The fault is that it is NOT an instrument that can protect us from oppression if we ourselves are not willing to take a hand in defending it.
