[Bill of Rights]
The conventions of a number of the States having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added.
Yeah, the BOR, just more words to misconstrue. First amendment? McCain Feingold and "separation of church and state" has the government PROHIBITING the exercise of religion, in direct conflict with the words of the 1st. Second amendment? Small arms, if kept at home. No military grade stuff for the public - again in direct conflict with the BOR.
At bottom, the guard against misconstruction can only be an informed, freedom-loving (i.e., personally independent), demanding populace.
That isn't going to magically appear, and I believe the republic is beyond salvage. I see about three people in Congress (out of 535) who might, maybe, be serious about giving the people their freedom back. The others just disagree on exactly how the feds might implement action to best "help."
